I want to ask you if it is possible with .htaccess to remove "http://" from url query parameter. What I mean is that I have website http://MyWebsite.com and I am passing a url query parameter on two of the pages like this http://MyWebsite.com/Page/?url=www.AnotherWebsite.com. It is wordpress website and it doesn't allow me to pass parameter with "http://" in it. It simply doesn't work then. I try to reassure that such a parameter will never be pass, but it's pain in the ass and I simply can't be 100% sure. Is it possble to remove "http://" from parameter if existing with mod rewrite? So that it would redirect http://MyWebsite.com/Page/?url=http://w ... ebsite.com to http://MyWebsite.com/Page/?url=www.AnotherWebsite.com and not doing anything if http in parameter doesn't exist.
