rewriterule facing problem

[shamsuljewel]

Hi

I have a URLs of my existing site like www.ex.com/content.php?page=client-list

now i make a rewriterul on .htaccess file

RewriteRule content/page/(.*)/ content.php?page=$1

it works fine as www.ex.com/content/page/client-list

 

but i have URLs also like this www.ex.com/content.php?page=client-list&client=overseas

 

and i am using this code

RewriteRule content/(.*)/client/(.*)/ content.php?page=$1&client=$2

but this is not working but if i remove the first rewriterule removed then it works fine..

so can any one help me how to do that???
