help with htaccess query strings appending constantly

I have an htaccess rule that goes:

RewriteRule ^Commercial-Units/For-Sale/(([a-zA-Z]+)*/([0-9]+)*/([a-zA-Z]+)*/([0-9]+)*/([a-zA-Z]+)*/([0-9]+)*)*$ pages/index.php?f=quicksearch&cust_wants=1&want_type=2&at=$3&start=$5&limit=$7 [R=302,L]  

This is specifically designed for when a page requires paging records.

I have been trying to fi开发者_如何学Gond solutions over everywhere in Google and Stackoverflow.com..

The problem is that everytime someone clicks on, say page 2, the address bar keeps on adding my query strings like so:

http://mysite.com/Commerial-Units/For-Sale/page/2/at/10/limit/7/page/2/at/10/limit/7

notice that the url above containes multiple key-value combinations duplicated and this goes on and on everytime someone clicks on the next page...

Hope someone can point me to the right solution to this...

Thank you very much!

Thats not a problem with your rewrite but with your site code the links are adding /page/2/at/10/limit/7 to the current url you need to remove the previous params using something like ../../../../../../page/2/at/10/limit/7

And if that is for SEO please use parameters for pagination, only use SEO friendly urls for categories and items, no need to index every single pagination option, as that will be duplicated content.
