This is a parallel question to another I'd posted here.
We have an issue with SharePoint 2007 and relative URLs through an Apache Reverse Proxy.
The issue comes in using a regex to find all the different types of relative URLs that SharePoint uses and getting them passed through the reverse proxy correctly (our internal site is like internal.site.com, and the external site is like external.site.com/internalsite).
I had a thought: Converting would be simpler if we were always working with absolute URLs.
So, my question in its entirety is: across HTML, CSS, JavaScript, headers, etc. What is the best way to take every relative URL and turn it into an absolute URL?
Note: My team is largely unfamiliar with Apache, so I'm hoping an answer would include helping us select what is the right module for this solution (mod_publish? mod_proxy_html? etc.)
Thanks in advance for any help you can give!
