Comparing values in RewriteCond directive

[alchemist vk <alchemist.vk@xxxxxxxxx>]

Hi All,

   I have one test uri 'http://example.com/test1.test2'.   How I can fetch uri components test1 and test2 and compare them via RewriteCond directive?..

I tried like below:

   RewriteCond {REQUEST_URI} http://example.com/(.*)\.(.*)

   RewriteCond $1!=$2

But getting syntax error saying $1!=$2 is not proper syntax..

With Regards,

Venkatesh
