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:
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!
