Apache as Reverse Proxy for UWC and Webmail

Question

Hi,
for several reasons i want to use apache 2 as reverse proxy and ssl accelerator for UWC.
internet <-> apache/ssl <-> backend port 80
I configured my apache with mod_proxy and mod_proxy_html.
Here are the concerning config lines:
LoadModule headers_module modules/mod_headers.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadFile    /usr/lib/libxml2.so
LoadModule  proxy_html_module    modules/mod_proxy_html.so
ProxyPass / http://backend.domain.com/
ProxyPassReverse / http://backend.domain.com/
<Location />
        ProxyPassReverse /
        SetOutputFilter proxy-html
        ProxyHTMLURLMap / /
        ProxyHTMLURLMap http://backend.domain.com:80/ http://webplex.domain.com/
        ProxyHTMLExtended On
        RequestHeader unset Accept-Encoding
</Location>For Webmail this configuration works most of the time. There are some minor problems in ie with the folder view. But the real problem is: I can't get UWC to work. The problem seems to be that mod_proxy_html can't replace all of the occurences of backend.domain.com in the html pages.
Especially:
onsubmit="handleSubmit()" action="http://webplex.domain.com/amserver/UI/Login?goto=http://backend.domain.com:80/uwc/&gotoOnFail=http://backend.domain.com:80/uwc/?err=1&module=LDAP" method="POST">in the uwc login page.
So my question is:
Is anybody out there who got apache working as reverse proxy for uwc?
Thanks a lot.
PS1:Solaris 10 on V20z, JES2005Q4
PS2: I already configured UWC with the reverse plugin for sun webserver on backend host so that uwc is working through port 80 only. So there should be no problems arise from that.

Answer 1

Hopefully, you'll hear from somebody. I have zero knowledge or experience with Apache.
