Hello,
This might not be the most appropriate forum to field this question - but
I'm having serious issues with the formulation of a regex for Mod Rewrite. I
actually have a couple of questions to ask :
1> What is particular flavor of the regex engine being used by Mod Rewrite -
there are ever so slight variations in the different regex engines, e.g.
linux grep vs perl grep etc.
2> I'm having trouble formulating a good compact regex to represent the
following problem :
I want my RewriteCond to be conditioned on the %{QUERY_STRING} to contain
only the powerset of a group of words e.g.
Hence if my set is say {rain,spain,plain}
The RewriteCond should say yes to the following :
http://foo.bar.com/?Operation=rain,spain
http://foo.bar.com/?Operation=plain,rain,rain
http://foo.bar.com/?Operation=plain,rain,spain
But not :
http://foo.bar.com/?Operation=rain,spain,mainly
Help please ?
