Hello Henrik, thanks for your answer,

The webserver is located at the same switch and can be reached perfectly (see the quotation mark example) from looking at the webserver logfile I can see, that squid does not even try to contact the webserver for a refresh. this underlines my idea, that squid believes it has got a "good copy" of the page. > You can also use the PURGE method to completely remove any traces of this > object from Squid, but it should not make any difference to the above. > I will have this PURGE method tested as soon as I encounter this problem again... yet, I can't force this problem .... BTW: maybe "7.5 How can I purge an object from my cache? " in the faq should be changed into "How can I delete an object from my cache?" ... I was always googling for "deleting" not "purging" ... kind regards, henrik steffen
