I wrote an extension for Chrome that allows you to send some authentication headers to the internal system. Now some colleagues have asked me if I can provide this add-on for Safari. My addon also includes some kind of internal address book for finding people in our company.
While the address book functionality works fine in Safari, I can't find a way to add some HTTP headers (I don't need to manipulate existing headers, just add some more attributes like USERID ). Is this possible with Safari?
