    copied!<p>You can <em>only</em> get rid of this client-side.</p> <p>You might think that you could solve this server-side by redirecting to a URL without the anchor:</p> <ul> <li>facebook redirects to <code>http://MyFacebookRedirectUrl...#_=_</code></li> <li>Then we redirect to some new URL, without the anchor</li> </ul> <p>....But the <code>#_=_</code> reappears by magic in the browser address bar - how?</p> <p>See James Pearce's answer at <a href="http://developers.facebook.com/bugs/318390728250352" rel="nofollow">http://developers.facebook.com/bugs/318390728250352</a> :</p> <p><em>"Some browsers will append the hash fragment from a URL to the end of a new URL to which they have been redirected (if that new URL does not itself have a hash fragment)."</em></p> <p>and also this:</p> <p><a href="http://blogs.msdn.com/b/ieinternals/archive/2011/05/17/url-fragments-and-redirects-anchor-hash-missing.aspx" rel="nofollow">http://blogs.msdn.com/b/ieinternals/archive/2011/05/17/url-fragments-and-redirects-anchor-hash-missing.aspx</a></p> <blockquote> <p>Firefox, Chrome, and Opera [and now IE10] will re-attach a URL Fragment after a HTTP/3xx redirection has taken place, even though that fragment was not present in the URL specified by the Location header on the redirection response</p> </blockquote> <p>So if you're just doing server side redirects from your Facebook redirect page, you're going to have to remove this client-side.</p> <p>The other alternative is to redirect server-side to a URL that contains a different named anchor - but that doesn't really solve the problem and not all browsers will do the same thing.</p>
