mod_substitute is included in later Apache's and does a great job. I actually like it better than mod_proxy_html, since the latter has a tendency to rewrite a _lot_ of stuff to make it "valid" HTML/XHTML.
Not that that's necessarily a terrible thing, but sometimes I just want to change what I told it to change...
I used the SRPM from RHWAS to update to the latest Apache on EL5.
Great, the issue I am getting is the browser doesn't understand the rewritten content as a result of xhtml issues.
Rh's ftp shows httpd-2.2.8-1.el5s2.src.rpm for this rpm as latest.
I'll give a go at compiling this to try mod_substitute.
Thanks guys! jlc
