An "example.com" Cookie will be sent to www.example.com and www1.example.com. Questions for troubleshooting: Is www.example.com receiving the Cookie? (Should be yes.) Is www.example.com sending the Cookie when proxying to www1.example.com? Is www1.example.com receiving the Cookie? (Both should be yes, but mod_proxy breaks in every other release. This 2.2.1 changes state this issue was fixed.) Does the server software on www1.example.com check the Domain field on incoming Cookies and ignore Cookies from parent domains? (Would mean overengineering. If the Cookie arrives, use it.) When you write "parameters", do you mean HTTP Headers, QueryString parameters, POST parameters, part of the URL, or something else? The parameters issue may require mod_rewrite. Ttry this: RewriteEngine On RewriteRule ^/site/(.*)$ http://www1.example.com/$1 [P] solprovider === From: Skiff Lad On: 20071002 14:59 I seem to have a problem / misunderstanding regarding the use of the ProxyPassReverseCookieDomain directive on 2.2.4 on Windows. I have www.example.com running 2.2.4. Within the httpd.conf file, I have a number of redirect directive statements that send a user, based on the URL, eg. www.example.com/site1 to www1.example.com etc. This all works fine so that the user arrives on the www1 box and there is a cookie correctly set with name www1.example.com It now transpires that I need to use ProxyPass to pass the parameters coming in on the request to www.example.com onto www1.example.com - as redirect doesn't send these initial parameters across. So, my httpd.conf file (on www.example.com) now looks like: ProxyPass /site1 http://www1.example.com ProxyPassReverse /site1 http://www1.example.com ProxyPassReverseCookieDomain www1.example.com www.example.com But nothing seems to be happening. When I access www.example.com/site1, there is a cookie correctly created (with the right contents etc), however, it is named simply example.com, ie. there is no www. nor www1. prefixing - this breaks subsequent processing on the www1.example.com box because there is no cookie named accordingly. What am I doing wrong ? Do I need anything else ? Or am I being plain stupid ?
