Can this mod rewrite be done?

I am using VCM interstitials on one of my sites.
AS you know these pop up between pages now and again and show an ad then redirect to the page the user was going to originally.
Lately there is a problem.
When a user clicks a link and an interstitial comes up it doesnt redirect to the correct page.
So instead os going to the correct page
ie:

http://www.mysite.com/newpage/

Code (markup):

it goes to

http://www.mysite.com/newpage/&upsid=872145573662

Code (markup):

The number is always the same so is there a way using htaccess to direct it to the correct page?
Thanks
MK

 

RewriteRule ^/newpage/$ /newpage/?upsid=872145573662 [L,NC]


that should work

 

Thanks powerspike
Will that work for all the links on the site or will I have to use a different one for every link?

 

The above rewrite rule will only work on the /newpage/ directory structor,

RewriteRule ^/(.*)/$ /$1/?upsid=872145573662 [L,NC]

that rull will make it work for all first level directory structors.
