Hello We are in the progress to replace our old Squid 2.4 caches with new ones. We testet on Ubuntu and Gentoo with Squid 2.7.x. Our setup includes a local Squid and a parent Squid in the DMZ where the local Squid connects to the parent with ICP. The parent Squid also serves the clients of ist subnet diretly. Everything is working fine with the new Squid, except one web site. When connecting to http://www.buero-schoch.ch the site starts loading, then the loading get stalled and after some minutes the site is loaded completly. In the logs, I couldn't find anything special. I used WGET to retrieve the headers: On the old Squid 2.4: HTTP request sent, awaiting response... 1 HTTP/1.1 200 OK 2 Content-Type: text/html;charset=iso-8859-1 3 Set-Cookie: fe_typo_user=fcdc25dec3; path=/ 4 Server: Oracle-Application-Server-10g/9.0.4.0.0 Oracle-HTTP-Server OracleAS-Web-Cache-10g/9.0.4.0.0 (N) 5 Connection: Close 6 Date: Fri, 27 Mar 2009 17:01:13 GMT 7 X-Powered-By: PHP/4.3.10 8 X-Pad: avoid browser bug 200 OK On the new Squid 2.7: HTTP request sent, awaiting response...

We have this behavior with both Squids of version 2.7 (Ubuntu and Gentoo). The problem seems to be with the version 2.7. It does not depend if I connect over the child -> parent squid or make a direct connect to the parent Squid from its subnet. Here is the configuration of the parent Squid, where the localnet can use it directly too.
