Dear Administrator, Please forgive us any crossposting of this message. If you are not the person responsible for WWW caching at your institution, please pass this on to whoever you think would be appropriate. Thank you. Enclosed you can find a survey form on operational caching systems in Europe. The survey is conducted by the Interdisciplinary Centre for Mathematical and Computational Modelling, Warsaw University which is hosting the Polish national caching project. By taking part in this survey, you will help to produce a more reliable and efficient caching infrastructure for Europe. This survey is regarded as a contribution to the European caching task force (for details about this initiative please refer to http://www.terena.nl/tech/projects/choc/). If this is feasible, we would ask you to fill out the online version of the survey, that is available at http://w3cache.icm.edu.pl/survey/ rather than responding by email, since this would greatly facilitate our gathering the results. Otherwise, send your answers to survey@icm.edu.pl. If you consider any questions to be sensitive or difficult to answer, feel free to skip them. Results of the survey will be published at http://w3cache.icm.edu.pl/survey/results/ Thank you very much for your time, John Martin Wojtek Sylwestrzak --SURVEY STARTS HERE-- ### Section 1 - General questions 1.1 Primary contact information First name : Last name : Title : Institution : E-mail : Street address : City : Code : Country : 1.2 Your hosting institution is a: [ ] College/high school [ ] University/research institute [ ] Governmental institution [ ] Internet service provider [ ] Other commercial [ ] Other, please specify: 1.3 What is the URL of your service ? 1.4 Would you like your service to be added to a public list of caches for your region ?
