Problems with ProxyPassReverseCookieDomain (Apache Users)

Hi,

I seem to have a problem / misunderstanding regarding the use of the ProxyPassReverseCookieDomain directive on 2.2.4 on Windows.

I have www.mydomain.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.mydomain.com/site1 to www1.mydomain.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.mydomain.com

So far so good.

It now transpires that I need to use ProxyPass to pass the parameters coming in on the request to www.mydomain.com onto www1.mydomain.com - as redirect doesn't send these initial parameters across.

So, my httpd.conf file (on www.mydomain.com) now looks like:

ProxyPass /site1 http://www1.mydomain.com

ProxyPassReverse /site1 http://www1.mydomain.com

I also added the following ProxyPassReverseCookieDomain directive:

ProxyPassReverseCookieDomain www1.mydomain.com www.mydomain.com

But nothing seems to be happening. When I access www.mydomain.com/site1, there is a cookie correctly created (with the right contents etc), however, it is named simply mydomain.com, ie. there is no www. nor www1. prefixing - this breaks subsequent processing on the www1.mydomain.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 ?

Thanks
