Hi there, I do not know much about squid, so please be patient with me .. I have a (Zope based) CMS for which I want to provide a squid accelerator. The squid config file is generated by an utility. You find it attached. To test it I generated an entry in the hosts file: 127.0.0.1 testiste.zehndercom.org when I try to access the testsite running at port 8080 directly things work fine. However When I access it trough squid I get an error: While trying to retrieve the URL: http://127.0.0.1:8080/VirtualHostBase/http/testsite.zehndergroup.com:80/zehnderi/zehnderi/VirtualHostRoot/front-page The following error was encountered: * Unable to forward this request at this time. I d add an excerpt from the cache.log . what could created this error what need I to do to avoid it. thanks in advance robert here the squid.conf. -------------------- # This configuration file requires squid 2.6+.
