Whitelist HTTP Referrer header

Is it possible to exclude sites when the option “Do not allow websites to know where you came from (suppress HTTP Referrer header)” is checked?

Some site do not work correctly when this options is checked (f.e. Experts-Exchange).

I believe it is all or nothing with this option. You may wish to go with an extension, such as NOREF. It allows you to whitelist URL’s.

I looked at the extension, but it changes all URL’s found on every loaded page. This could be a seriously performance impact whereas the build in method by CD works differently (only when clicking a link?) and so i believe much less performance impact?
