Bluehost : htaccess redirect question

This is a bluehost question posted by hofmax on 04 September 2006

I want to completely redirect my site structure and I want to redirect the urls to the homepage until the new page is ready.

So suppose I have links such as http://www.mysite.com/chat/language=greek+user=new

http://www.mysite.com/AdvancedGuestB….php?gb_id=724

So I wanted to try to redirect the respective folder /chat or /AdvancedGuestBook and everything thereafter using regular expressions

for the first example I tried this:

RewriteCond %{HTTP_HOST} ^/chat*
RewriteRule ^(.*)$ http://www.mysite.com$ [R=301,L]

These are supposed to be permanent redirects.
Can anybody tell me what the syntax with regex is for redirecting everything after chat or advancedguestbook ?
