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
