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
