[users@httpd] Proxying GET and POST requests

[wi <ic...@gmail.com>]

Hi all

We have a need (driven by some load/caching issues) to split our incoming
traffic so that GET requests go to one set of servers and POST requests go
to another part of the farm. Unfortunately, there's no simple URI based way
of identifying which is which, so I'm wondering whether there is some way to
do this that I've missed.

I imagine it would be possible to come up with a mod_perl solution to this,
but if there's some sort of simple "Pure Apache" way, I'd like to try that
first.

thanks
Wayne

If you're using mod_proxy you might be able to set up proxy instructions 
inside a pair <Limits>.


<LimitExcept POST>
	#do 'get', etc stuff
</LimitExcept>


<Limit POST>
	#do post stuff
</Limit>

mod_rewrite can do this, something like this:

RewriteCond %{REQUEST_METHOD} POST
RewriteRule /(.*) http://posthost.my.domain/$1 [P,L]
RewriteRule /(.*) http://gethost.my.domain/$1 [P]
