Waaay OT

[Andrew Kelly <akelly corisweb org>]

Hi all,

please, forgive the OT nature of this mail, I realize it has nothing to
do with RH. 
I've been googling an apparent rarity and having little luck, and
thought I'd try you all in a hail Mary pass. Perhaps one of you is
Apache guru enough to lend a hand.

My problem is, using Mod Rewrite, how do I access payloads? I'd love
access to POST variables as well, of course, but right now what I
primarily want to know is how can I catch the contents of a GET string
to use in a RewriteCond.

Concretely:

I have a calling URI of
http://domain.name/index.php?var1=value1&var2=value2&var3=value3

I want to redirect based on the value of a variable.

PseudoCode:
RewriteEngine On
RewriteCond %{GET_VARS} var2=value2
RewriteRule ^/$	http://new.domain.name/path [R,L]

Does anybody know the real code to make this happen?

Any help VERY much appreciated.

Andy
