[squid-users] Re: squid as forward proxy for portal run on tomcat

I placed my squid.conf at the end of this post.
Squid forward proxy works fine for all third party http and https sites, but
fails when I try to proxy this specific portal that I put up on tomcat.

This is the failure:
2011/03/22 07:02:03| Accepting bumpy HTTP connections at [::]:3128, FD 15.

Please advise,
