RE: [squid-users] Suspected bug - problems loading images with ICAP

It turned that the problem wasn't due Squid but to the ICAP Server we
used, which closed the connection after a "204" response although it
didn't send the "Connection: close" header.

Subject: [squid-users] Suspected bug - problems loading images with ICAP

Hi,
 
While trying to load pages web pages via Squid with ICAP respmod &
reqmod enabled,
parts of the page often fail to load (css/images). Squid reports ICAP
error 113.
However, the response from the ICAP server to both ICAP Reqmod and
Respmod requests are valid (we analyzed it using Ethereal)
Note: The problem did not happen when respmod is disabled.
