mod_proxy_html (reverse proxy) functionality for Apache 1

[Jim Brandt <cb...@buffalo.edu>]

I need to implement the reverse proxy link-fixing behavior provided in 
Apache 2 by mod_proxy_html:

http://apache.webthing.com/mod_proxy_html/

but I need it in Apache 1.

Some digging turned up Apache::ReverseProxy, which appears to have a 
nice spot in the code to access the response body before sending it back 
to the client.

Are there any other solutions for Apache 1 before I start hacking on 
this module? I need solutions that run through Apache because I need the 
auth provided by an existing Apache module.

Any issues other than dealing with an incorrect Content-length value?

Thanks,
Jim

Turns out I was able to munge the pages on the way back using 
Apache::ReverseProxy.

I did this by just hacking in my fixes, but I'm thinking this might be a 
useful feature to suggest to the author (with a patch, of course).

At first I thought to offer some of the same functionality as 
mod_proxy_html (just the URL rewriting part). But I ended up needed to 
modify more than just the URLs in the pages coming through. So I thought 
why not just accept a subroutine reference and run the data coming back 
through whatever code the user provides?

Any comments on that? What would be the best interface to define the 
subroutine reference? Any existing modules that accept this sort of 
configuration?

Thanks,
Jim

The Apache::Filter stuff does work, but I don't see any advantage to
using that in this case.  You'd still have to do the proxy fetch
yourself.
