Organizing websites is highly dynamic and often chaotic. Thus, it is crucial that host web servers manipulate URLs in order to cope with temporarily or permanently relocated resources, prevent attacks by automated worms, and control resource access.The Apache mod_rewrite module has long inspired fits of joy because it offers an unparalleled toolset for manipulating URLs. The Definitive Guide to Apache mod_rewrite guides you through configuration and use of the module for a variety of purposes, including basic and conditional rewrites, access control, virtual host maintenance, and proxies.This book was authored by Rich Bowen, noted Apache expert and Apache Software Foundation member, and draws on his years of experience administering, and regular speaking and writing about, the Apache server.

Pro Apache Ant is ideal for Java developers who need to use the leading open source build tool out there for development and project management. It is organized around chronological tasks instead of alphabetical functions, using a sample application throughout the set-up, from calling database scripts to unit testing.Practical examples are used at every stage and each task includes a concrete example. The configuration files are XML based, so there’s no need for you to write shell commands. Each task is run by an object that implements a particular task interface. And if you really need to execute a shell command, Ant has a task that allows different commands based on the operating system.

Practical Mono offers a detailed portrait of Mono and its many facets. You’ll learn about building GUI-based applications with Gtk#, database interaction with ADO.NET, and powerful applications with XML and web services.By embracing this implementation, you can take advantage of the powerful development paradigm, building Internet-enabled cross-platform applications based on open source technologies. This book includes a primer on C#, so even if you’re a novice .NET programmer, you will still gain plenty from this practical guide.

Last, but not least, thanks to all the participants and authors. We hope that they enjoyed the workshop as much as the wonderful and culturally vibrant city of Kolkata! Bhabani P. Sinha Indian Statistical Institute, Kolkata, India December 2004 Sajal K. Das University of Texas, Arlington, USA December 2004 Program Chairs' Message On behalf of the Technical Program Committee of the 6th International Wo- shop on Distributed Computing, IWDC 2004, it was our great pleasure to w- come the attendees to Kolkata, India. Over the last few years, IWDC has emerged as an internationally renowned forum for interaction among researchers from academia and industries around the world. A clear indicator of this fact is the large number of high-quality submissions of technical papers received by the workshop this year. The workshop program consisted of 12 technical sessions with 54 contributed papers, two keynote addresses, four tutorials, a panel, a poster session and the Prof.A.K.ChoudhuryMemorialLecture.TheIWDCProgramCommittee,c- prising 38 distinguished members, worked hard to organize the technical p- gram. Following a rigorous review process, out of 157 submissions only 54 - pers were accepted for presentation in the technical sessions; 27 of the accepted papers were classi?ed as regular papers and the remaining 27 as short papers. Another 11 papers were accepted for presentation in the poster session, each with a one-page abstract appearing in the proceedings.

The 10th Annual ASIACRYPT 2004 was held in Jeju Island, Korea, d- ing December 5-9, 2004. This conference was organized by the International Association for Cryptologic Research (IACR) in cooperation with KIISC (- rean Institute of Information Security and Cryptology) and IRIS (International Research center for Information Security) at ICU (Information and Communi- tionsUniversity),andwas?nanciallysupportedbyMIC(MinistryofInformation and Communication) in Korea. The conference received, from 30 countries, 208 submissions that represent the current state of work in the cryptographic community worldwide, covering all areas of cryptologic research. Each paper, without the authors' information, was reviewed by at least three members of the program committee, and the papers (co-)authored by members of the program committee were reviewed by at least six members. We also blinded the reviewers' names among the reviewers until the ?nal decision, by using pseudonyms. The reviews were then followed by deep discussions on the papers, which greatly contributed to the quality of the ?nal selection. In most cases, extensive comments were sent to the authors. Among 208 submissions, the program committee selected 36 papers. Two submissions were merged into a single paper, yielding the total of 35 papers acceptedforpresentationinthetechnicalprogramoftheconference.Manyhi- quality works could not be accepted because of the competitive nature of the conference and the challenging task of selecting a program. These proceedings contain revised versions of the accepted papers. These revisions have not been checked for correctness, and the authors bear full responsibility for the contents of their papers.

Grid and cooperative computing has emerged as a new frontier of information tech- logy. It aims to share and coordinate distributed and heterogeneous network resources forbetterperformanceandfunctionalitythatcanotherwisenotbeachieved.Thisvolume contains the papers presented at the 2nd International Workshop on Grid and Coope- tive Computing, GCC 2003, which was held in Shanghai, P.R. China, during December 7-10, 2003. GCC is designed to serve as a forum to present current and future work as well as to exchange research ideas among researchers, developers, practitioners, and usersinGridcomputing,Webservicesandcooperativecomputing,includingtheoryand applications. For this workshop, we received over 550 paper submissions from 22 countries and regions. All the papers were peer-reviewed in depth and qualitatively graded on their relevance, originality, signi?cance, presentation, and the overall appropriateness of their acceptance. Any concerns raised were discussed by the program committee. The or- nizing committee selected 176 papers for conference presentation (full papers) and 173 submissions for poster presentation (short papers).The papers included herein represent the forefront of research from China, USA, UK, Canada, Switzerland, Japan, Aust- lia, India, Korea, Singapore, Brazil, Norway, Greece, Iran, Turkey, Oman, Pakistan and other countries. More than 600 attendees participated in the technical section and the exhibition of the workshop.

The Cryptographers' Track (CT-RSA) is a research conference within the RSA conference, the largest, regularly staged computer security event. CT-RSA 2004 was the fourth year of the Cryptographers' Track, and it is now an established venue for presenting practical research results related to cryptography and data security. The conference received 77 submissions, and the program committee sel- ted 28 of these for presentation. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to cryp- graphy. Each paper was reviewed by at least three program committee members. Extended abstracts of the revised versions of these papers are in these proc- dings. The program also included two invited lectures by Dan Boneh and Silvio Micali. I am extremely grateful to the program committee members for their en- mous investment of time and e?ort in the di?cult and delicate process of review and selection. Many of them attended the program committee meeting during the Crypto 2003 conference at the University of California, Santa Barbara.

The mid-1990ssaw an exciting convergenceof a number of dieren t information protection technologies, whose theme was the hiding (as opposed to encryption) of information. Copyright marking schemes are about hiding either copyright notices or individual serial numbers imperceptibly in digital audio and video, as a component in intellectual property protection systems; anonymous c- munication is another area of rapid growth, with people designing systems for electronic cash, digital elections, and privacy in mobile communications; se- rity researchers are also interested in 'stray' communication channels, such as those which arise via shared resourcesin operating systems or the physical le- age of information through radio frequency emissions; and n ally, many workers in these elds drew inspiration from 'classical' hidden communication methods such as steganography and spread-spectrum radio. The rst international workshop on this new emergent discipline of inf- mation hiding was organised by Ross Anderson and held at the Isaac Newton Institute, Cambridge, from the 30th May to the 1st June 1996, and was judged by attendees to be a successful and signi cant event. In addition to a number of research papers, we had invited talks from David Kahn on the history of steganography and from Gus Simmons on the history of subliminal channels. We also had a number of discussion sessions, culminating in a series of votes on common terms and de nitions. These papers and talks, together with minutes of the discussion, can be found in the proceedings, which are published in this series as Volume 1174.

This book constitutes the refereed proceedings of the Third International Conference on Embedded Software, EMSOFT 2003, held in Philadelphia, PA, USA in October 2003.The 20 revised full papers presented together with three invited papers were carefully reviewed and selected from 60 submissions. All current topics in embedded software are addressed: formal methods and model-based development, middleware and fault tolerance, modelling and analysis, programming languages and compilers, real-time scheduling, resource-aware systems, and systems on a chip.

This volume contains the proceedings of the 7th International Workshop on Software and Compilers for Embedded Systems, SCOPES 2003, held in Vienna, Austria, September 24-26, 2003. Initially, the workshop was referred to as the International Workshop on Code Generation for Embedded Systems. The ?rst workshop took place in 1994 in Schloss Dagstuhl, Germany. From its beg- nings, the intention of the organizers was to create an atmosphere in which the researcherscould participateactively in dynamic discussionsand pro?t from the assembly of international experts in the ?eld. It was at the fourth workshop, in St. Goar, Germany, in 1999, that the spectrum of topics of interest for the workshop was extended, and not only code generation, but also software and compilers for embedded systems, were considered. The change in ?elds of interest led to a change of name, and this is when the present name was used for the ?rst time. Since then, SCOPES has been held again in St. Goar, Germany, in 2001; Berlin, Germany, in 2002; and this year, 2003, in Vienna, Austria. In response to the call for papers, 43 very strong papers from all over the world were submitted. The program committee selected 26 papers for pres- tation at SCOPES 2003. All submitted papers were reviewed by at least three experts in order to ensure the quality of the work presented at the workshop.

The 2003 Information Security Conference was the sixth in a series that started with the InformationSecurity Workshopin 1997.A distinct feature of this series is the wide coverage of topics with the aim of encouraging interaction between researchers in di?erent aspects of information security. This trend continued in the program of this year's conference. There were 133 paper submissions to ISC 2003. From these submissions the 31papersintheseproceedingswereselectedbytheprogramcommittee,covering a wide range of technical areas. These papers are supplemented by two invited papers;athirdinvitedtalkwaspresentedattheconferencebutisnotrepresented by a written paper. We would like to extend our sincere thanks to all the authors that submitted papers to ISC 2003, and we hope that those whose papers were declined will be able to ?nd an alternative forum for their work. We are also very grateful to the three eminent invited speakers at the conference: Paul van Oorschot (Carleton University, Canada), Ueli Maurer (ETH Zur * ich, Switzerland), and Andy Clark (Inforenz Limited, UK). We were fortunate to have an energetic team of experts who took onthe task of the program committee. Their names may be found overleaf, and we thank them warmly for their considerable e?orts. This team was helped by an even larger number of individuals who reviewed papers in their particular areas of expertise. A list of these names is also provided, which we hope is complete.

UbiComp 2003, the 5th Annual Conference on Ubiquitous Computing, is the premier forum for presentation of research results in all areas relating to the - sign, implementation, deployment and evaluation of ubiquitous computing te- nologies. The conference brings together leading researchers, from a variety of disciplines, perspectives and geographical areas, who are exploring the impli- tions of computing as it moves beyond the desktop and becomes increasingly interwoven into the fabrics of our lives. This volume, the conference proceedings, contains the entire collection of high-quality full papers and technical notes from UbiComp 2003. There were 16 full papers in this year's conference, selected by our international program committee from among 117 submissions. There were also 11 technical notes in the program: 8 taken from the 36 technical note submissions, and 3 that were adapted from full paper submissions. We are very grateful to Tim Kindberg and Bernt Schiele, our Technical Notes Co-chairs, and to all the authors and reviewers of both papers and technical notes who contributed to maintaining the high standards of quality for the conference. In addition to the full papers and technical notes, UbiComp 2003 also p- vided a number of other participation categories, including workshops, dem- strations, interactive posters, a panel, a doctoral colloquium and a video p- gram. While accepted submissions in these categories were also of high quality, timing and size constraints prevented us from including them in this volume.

Welcome to the proceedings of the 6th IEEE International Conference on Mobile Agents. MA 2002 took place in Barcelona, Spain and was co-located with the 4th International Workshop on Mobile Agents for Telecommunications Applications. Both events were held at the Universitat Pompeu Fabra, October 22-25, 2002. Mobile agents may be de?ned as programs that, with varying degree of - tonomy, can move between hosts across a network. Mobile agents combine the notions of mobile code, mobile computation, and mobile state. Capabilities of mobile agents include: - Supporting unrealiable networks and disconnected operation - Counteracting low-bandwidth, high-latency communication links - Deploying newbehaviour (through mobile code) and recon?guring systems on-the-?y - Distributing processing load across systems - Improving survivability in the face of network and system failure. Given the above capabilities, mobile agents (while they may not be referred to as such) are nowbecoming accepted as a fundamental architectural construct for the design and development of complex adaptive systems that need to operate in highly dynamic environments. Mobile agents also support applications in several domains such as ubiquitous computing, grid computing, remote sensing, data mining, system management, and agile computing.

This book constitutes the thoroughly refereed post-proceedings of the 6th International Workshop on Open Hypermedia Systems, OHS-6, and the 2nd International Workshop on Structural Computing, SC-2, held at the 11th ACM Conference on Hypertext and Hypermedia in San Antonio, Texas, USA in May/June 2000.The 19 revised full papers presented were carefully reviewed and selected for inclusion in the book. All current issues on open hypertext systems and structural computing are addressed.

his book presents the refereed proceedings of the 6th European Symposium on Research in Computer Security, ESORICS 2000, held in Toulouse, France in October 2000.The 19 revised full papers presented were carefully reviewed and selected from a total of 75 submissions. The papers are organized in sections on personal devices and smart cards, electronic commerce protocols, access control, protocol verification, Internet security, security property analysis, and mobile agents.

Since 1998, RAID has established its reputation as the main event in research on intrusion detection, both in Europe and the United States. Every year, RAID gathers researchers, security vendors and security practitioners to listen to the most recent research results in the area as well as experiments and deployment issues. This year, RAID has grown one step further to establish itself as a well-known event in the security community, with the publication of hardcopy proceedings. RAID 2000 received 26 paper submissions from 10 countries and 3 continents. The program committee selected 14 papers for publication and examined 6 of them for presentation. In addition RAID 2000 received 30 extended abstracts proposals; 15 of these extended abstracts were accepted for presentation. - tended abstracts are available on the website of the RAID symposium series, http://www.raid-symposium.org/. We would like to thank the technical p- gram committee for the help we received in reviewing the papers, as well as all the authors for their participation and submissions, even for those rejected. As in previous RAID symposiums, the program alternates between fun- mental research issues, such as newtechnologies for intrusion detection, and more practical issues linked to the deployment and operation of intrusion det- tion systems in a real environment. Five sessions have been devoted to intrusion detection technology, including modeling, data mining and advanced techniques.

This is the first book designed to help Windows developers decide not only which technologies to use but also how to use them. It teaches them to combine the wide variety of technologies that make up Windows DNA into effective solutions for their own enterprise application requirements. The author makes use of his long consulting experience in the client-server world to describe "best practices" that apply to building Windows DNA applications.

The EUROCRYPT '96 conference was sponsored by the International Asso- ation for Cryptologic Research (IACR)l, in cooperation with the University of Saragossa. It took place at the Palacio de Congresos in Saragossa, Spain, during May 12-16, 1996. This was the fifteenth annual EUROCRYPT conference (this name has been used since the third conference held in 1984), each of which has been held in a different city in Europe. For the second time, proceedings were available at the conference. JosC Pastor Franco, the General Chair, was resp- sible for local organization and registration. His contribution to the snccess of the conference is gratefully acknowledged. The Program Committee considered 126 submitted papers and selected 34 for presentation. Each paper was sent to all members of the Program Committee and was assigned to at least three of them for careful evaluation. There were also two invited talks. James L. Massey, this year's IACR Distinguished Ltcturer, gave a lecture entitled "e;The difficulty with difficulty"e;. Massey is the third to receive this honor, the first two being Gustavus Simmons and Adi Shamir. Shafi Goldwasser gave an invited talk entitled "e;Multi party secure protocols: past and present"e;. These proceedings contain revised versions of the 34 contributed talks. While the papers were carefully selected, they have not been refereed like submissions to a refereed journal. The authors bear full responsibility for the contents of their papers. Some authors may write final versions of their papers for publication in a refereed journal.
