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.
Information:
-------------
Version: Squid Stable11+ICAP+Null cache.
Configuration mainlines: no caching (including no memory caching), icap
resp/reqmod on all traffic.
