Mod_rewrite too many redirects

Hi,

I am trying to achieve below redirection rule:
http://localhost/?1234ab
this url should be redirected to below url:
http://localhost/welcome?trackFor=0&trackNo=1234ab
(where welcome?trackFor=0trackNo= always remains same)

Here you can see at the end, the query string is passed same as in source
url i.e. 1234ab

I wrote the below Rewrite rule and condition:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} (.*(([0-9]+).*)) [NC]
RewriteRule ^(.*)$ /welcome?trackFor=0&trackNo=%1 [L,R=302,QSD]
</IfModule>

When I hit the source URL in browser: http://localhost/?1234ab

I receive, too many redirects error in browser and page keeps on loading.

Am I missing something in mod_rewrite?

Cheers

-Vicky

The rule matches the target of the redirect, so it will loop.
If the rule is only valid for requests to "/?:

If the rule is in virtual host context
RewriteRule ^/$ /welcome?trackFor=0&trackNo=%1 [L,R=302,QSD]
If the rule is in htaccess, location, or other sections:
RewriteRule ^$ /welcome?trackFor=0&trackNo=%1 [L,R=302,QSD]
