Subject Re: [users@httpd] How to prevent mod_proxy from rewriting redirects into absolute URLs?
Date Mon, 19 Nov 2012 01:55:19 GMT
This is not an option because the point of my using the proxy in this
case is that I need to rewrite the URLs and content (with
mod_proxy_html). The app server hosts at / and I need to translate it
to a subdirectory /sub.
