Welcome to the 6th International Web Caching and Content Delivery Workshop. This workshop series has established itself as a premier gathering of researchers and practitioners in the area of Web scalability. This year, we received a record 61 submissions, of which 21 were chosen to be presented as full-length papers and 4 as project synopses. We wish to thank the authors of selected submissions as well as those whose papers could not be accomodated in the program. In addition to technical papers, the workshop program includes three panels covering some of the hottest and/or most controversial topics in this field. We are grateful to the distinguished panelists for sharing their thoughts.
While the workshop has grown and matured over the years, it retains its character as an informal meeting that encourages spontaneous exchange of ideas. Another tradition of this workshop series, reinforced again this year, is the high degree of interaction between industry and academia.
This year's workshop is being held on the campus of Boston University, in the heart of Boston. Many people worked hard to make this workshop a success. We would like to thank them all. In particular, we would like to thank members of the program committee, who helped create a very strong program, and the steering committee, who were always there whenever we needed an advice or encouragement. We also thank all external reviewers for helping us deal with the unexpectedly high number of submissions. The generous financial support from our industrial sponsors allowed us to keep registration fees low, especially for students. This year, our sponsors included CISCO Systems, Infolibria Inc., Measurement Factory Inc., and Volera Inc. Our sincere thanks go to them. Finally, we would like to acknowledge the Computer Science Department at Boston University for its support as the workshop's host.
The Internet and the Web continue to grow. It is exciting to witness and contribute to this phenomenon. We hope you will find your participation in this workshop an enjoyable and fruitful experience.
