quick read of your mail

arent you missing the ProxyPassReverse directive?

Hi,

I have a very big problem with ReverseProxy and CGI/PHP http-redirects.

I have three domains, e.g. domainEXT.xy, domainINT1.xy and domainINT2.xy
(The INT domains are on another server)
For domainEXT.xy i hafe a SSL-cert. (https://domainEXT.xy) works fine.

So i had the idea to make a ReverseProxy for the another 2 domains, 

to make them secure.

E.g.
https://domainEXT.xy/domainINT1.xy/
https://domainEXT.xy/domainINT2.xy/

On Apache 2.0.54/win32 i activeted now mod_proxy, mod_proxy_http, 

mod_proxy_connect and mod_proxy_html

And wrote the folowing in the httpd.conf
<VirtualHost ...:443>
 ServerName domainext.xy
 ### SSL config here ###
 ProxyRequests off
 ProxyPass /domainint1.xy/ http://domainint1.xy/
 ProxyHTMLURLMap http://domainint1.xy /domainint1.xy
 <Location /domainint1.xy/>
   ProxyPassReverse /
   SetOutputFilter proxy-html
   ProxyHTMLURLMap / /domainint1.xy/
   ProxyHTMLURLMap /domainint1.xy /domainint1.xy
   RequestHeader unset Accept-Encoding
 </Location>
 ProxyPass /domainint2.xy/ http://domainint2.xy/
 ProxyHTMLURLMap http://domainint2.xy /domainint2.xy
 <Location /domainint2.xy/>
   ProxyPassReverse /
   SetOutputFilter proxy-html
   ProxyHTMLURLMap / /domainint2.xy/
   ProxyHTMLURLMap /domainint2.xy /domainint2.xy
   RequestHeader unset Accept-Encoding
 </Location>
 Options -Indexes MultiViews
 DirectoryIndex index.php
 DocumentRoot "/web/public/"
</VirtualHost>

This works realy fine, but:

Now i hafe a script on http://domainINT2.xy/file.php in this file 

there is a header redirect:

HTTP/1.1 302
Location: http://domainINT2.xy/file2.php

Without the Proxy it will work, but if i call 

https://domainEXT.xy/domainINT2.xy/file.php it makes also a redirect 

to http://domainINT2.xy/file2.php and not to 

https://domainEXT.xy/domainINT2.xy/file2.php

Now my question:

How can i say mod_proxy* also to rewrite this Location headers if in 

it the domain name?

(cos i can't modify the scripts of the domainINT* domain names.)
I am shure this must work, but i don't know how?

I hope you can help please, and sorry for my bad english!

Greetings
Michael
