RewriteRule on args

[johnnypoll]

If I have:

RewriteRule (.*)this(.*) $1that$2

then

www.mysite.com/this becomes www.mysite.com/that

but

www.mysite.com?this=3 does NOT become www.mysite.com?that=3 at least on my apache installation

How can I do substitutions on the bits of the URL after the question mark i.e. on the parameters?

Thanks
John

The syntax you need is something like the following:

RewriteCond %{QUERY_STRING} "^this=(.*)" 
RewriteRule (.*)\.html$ /$1?that=%1 [R]

Good luck ;)
