htaccess redirect with ? in url

redirect htaccess

[ads112001]

Trying to redirect /link?fb=ms to /link.html
Using this redirect so in google analytics i can do a search for fb=ms and track how many visitors are coming from facebook to the site.

Right now in the .htaccess i'm using

Redirect /link?tw=ms http://www.website.com/index.php?offer=offer1

[BradleyT]

RewriteEngine On
RewriteCond %{REQUEST_URI} /link
RewriteCond %{QUERY_STRING} ^fb=ms$
RewriteRule ^(.*) http://www.example.com/index.php?offer=offer1? [R=301,L]

When the URI is /link and the query string is fb=ms send them to /index.php?offer=offer1.

yess thank you so much for your help that did it!

quick question. If i wanted to do multiple redirects, do i have to repeat the code for each? i.e. i wanted to use ?fb=ms and ?tw=ms would i have to repeat this for each?
RewriteEngine On
RewriteCond %{REQUEST_URI} /link
RewriteCond %{QUERY_STRING} ^fb=ms$
RewriteRule ^(.*) http://www.example.com/index.php?offer=offer1? [R=301,L]

ads112001 -- in BradlyT's example, you could use a regular expresion in the second condition to generalize the pattern being matched, e.g.

RewriteCond ${QUERY_STRING} ^(fb|tw)=ms$

Mastery of regular expressions is worth the effort, and I have seen some people get really proficient with them in as little as five to ten years :-). Fortunately, there's google -- try "regex examples" or "regexp examples".

(Or, because Google itself has operators that work similarly to regexp, try "regex|regexp examples" :-) )

A bit of optimization:

RewriteEngine on
#
RewriteCond %{QUERY_STRING} ^(fb|tw)=ms$
RewriteRule ^link$ http://www.example.com/?offer=offer1? [R=301,L]

Tip: Use

DirectoryIndex /index.php

(if not already configured) to map requests for the URL-path "/" to the filepath "/index.php", and do not mention "/index.php" in your on-page links or in redirects. It is unnecessary, wastes disk space and bandwidth, exposes your website technology, and will cause you to want to do a bunch of redirects if your site technology changes in the future. So linking to "/" is shorter, faster, safer, and will never need to change.
