Re: Reverse Proxying to 2 backends, how to keep the URL-directory prefix having relative paths?

Thanks a lot, but I am afraid that, in my case, *anything* can appear in 

the relative path, as it's a wiki and there is no prefix.

My guess is the following:

As is works for the first backend, this shows that Server/Browser *can* 

'remember' where to send a relative path to -- I guess by response 

parameters. So, although two hrefs in *.html files of two different 

backends a.net, b.net may be identical -- say 'page.html', the browser 

will glue it

a.net ++ / ++ page.html -> a.net/page.html
b.net ++ / ++ page.html -> b.net/page.html

To my impression, mod_proxy_html & mod_substitute replace the *relative 

href path* part, i.e.,

a.net ++ / ++ wiki/page.html

as explained, this is problematic.

What I am rather looking for is a substitution of the *response 

parameter path*, i.e.,

a.net/wiki ++ / ++ page.html

As this appears much simpler, I guess it might exist. Any ideas?

Thanks a lot, again,

    Nick

That article uses mod_proxy_html to rewrite URLs in the page body.

I have a similar setup and now use mod_substitute to do the same
thing. Much simpler and don't have to build the module separately (not
that its difficult). Upgrades are easier.

I prefer modules distributed as part of the Apache core.
