how to redirect request based wether a query string value is present?

Question

Hi,

I've searched and tried many examples but none seem to work for me. I need to redirect a request to a specific url depending on if the original request had a certain item in it's query string.

e.g.

www.mydomain.com/test.html?username=foo&password=bar

So I want to redirect this only is the username variable is present in the query string to

www.mydomain.com/home.html?username=foo&password=bar

But also, the page could be any page, .e.g test.html, home.html, contact.php

So if username variable is detected in query string, then the redirect will happen only.

thanks for your help.

I tried this but it did not work:

RewriteRule ^username(.*)$ test.html?username=$1 [L,QSA]

You can use QUERY_STRING to accomplish this.

RewriteCond %{QUERY_STRING} username
RewriteCond %{REQUEST_URI} !^/home.html
RewriteRule .* /home.html/ [L,QSA]
