[users@httpd] Apache Outputfilters

[Jack Saunders <ja...@gmail.com>]

I have been dealing with apache based reverse proxies for some time now and
I have come to conclusion that application code will always have absolute
links (ex. http://internal.servera.com/image.jpg or /image.jpg) and break
the proxies.  I am tired of having to argue with the code issues. So I am
looking into outputfilters to help me with this.

I have looked into the following outputfilters:
mod_sar
mod_proxy_html
mod_ext_filter
mod_perl2/ModProxyPerlHtml

I am currently needing a commerical support solution and thus far only
modules within the Apache distribution is supported.  I know mod_ext_filter
is meets this requirement, however I can see this being a major performance
bottleneck.

I hear some good things about mod_proxy_html but concerned with the
dependency of the external library.  Also no commercial support(Covalent).

Mod_sar does not have library dependencies, but again no commercial support,
that I have found.

ModProxyPerlHtml, no commercial support and does not seem to be heavily
used.

OK, my question to the list is what experiences and suggestions can you
guys/gals give on this?  Also I have plans to use mod_deflate and
mod_cache in conjunction so any issues?

Your time and help is very much appreciated!
