Rewriting Redirect 302 headers so that redirection goes through the

I am currently attempting to use my.domain.com as a proxy through which
users of my site access a business partners site:
http://domain.to_proxy_through_my_domain.com/

below is the configuration I have so far:

>#Load Files needed for proxy_html_module

Thus far it works until the point at which the user logs in to my
business partners domain
(http://domain.to_proxy_through_my_domain.com)


I used fiddler to track what happens during the request where the user logs=
in:

1. the browser makes the request to login:

>Request:

>POST /my-gateway/default.asp?do=3Dlogin HTTP/1.1
>Accept: image/gif, image/jpeg, image/pjpeg, application/x-ms-application, =
application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap=
, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/mswo=
rd, application/x-shockwave-flash, */*

>username=3Dtest&password=3Dtestpassword&Submit=3DLog+In


The response that the user gets back redirects them directly to my
business partners website, instead of through the proxy that I've
setup on my domain:

Use ProxyPassReverse, as described here:

http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypas sreverse
