URL Redirection - Services - Referrer Masking

Referrer Masking

Redirection services can hide the referrer by placing an intermediate page between the page the link is on and its destination. Although these are conceptually similar to other URL redirection services, they serve a different purpose, and they rarely attempt to shorten or obfuscate the destination URL (as their only intended side-effect is to hide referrer information and provide a clear gateway between other websites.)

This type of redirection is often used to prevent potentially-malicious links from gaining information using the referrer, for example a session ID in the query string. Many large community websites use link redirection on external links to lessen the chance of an exploit that could be used to steal account information, as well as make it clear when a user is leaving a service, to lessen the chance of effective phishing .

Here is a simplistic example of such a service, written in PHP.

Famous quotes containing the word masking:

    Love, love, love—all the wretched cant of it, masking egotism, lust, masochism, fantasy under a mythology of sentimental postures, a welter of self-induced miseries and joys, blinding and masking the essential personalities in the frozen gestures of courtship, in the kissing and the dating and the desire, the compliments and the quarrels which vivify its barrenness.
    Germaine Greer (b. 1939)
