Google and mod_rewrite

using mod_rewrite with safety

[jorje29]

I've made some SEO changes in my website and now, I'm using mod_rewrite. Do I've to remove all dynamic indexed pages from Google?

if yes, is this the right code for robots.txt file :

User-agent: Googlebot
Disallow: /*?

thanx in advance.

Yes, having the old query-string urls expire from Google is a good idea -- otherwise, the rewrite is only introducing duplicate urls for the same content - right?

The syntax you have for Googlebot is what Google always recommended in the past, although I can't find it on their newly organized webmaster information at present. Everyone who used it reported that it worked, but you should know that the use of a wildcard in a robots.txt rule is a specific syntax just for Googlebot. Wildcards are not part of the robots.txt standard.
