اقتبـاس ،، Send referrer information

Some Web sites register the site that referred you to them. This information can be used to tailor content based on the site that you came from. If you prefer not to allow a Web site to know where you were before visiting it, especially if you were on a local, secure, or restricted site, uncheck this option to disable it. Note, however, that some sites depend on referrer logging internally.
