Facebook appends #_=_ callack URL

After I have changed my getLoginUrl using php SDK with (array('redirect_uri' => $_SERVER['REQUEST_URI'],'s开发者_Python百科cope' => 'user_about_me')), still I facing problem with url appending #=.

Does anyone have answer for this problem? It happens only in Firefox and Chrome browsers.

This is to do with the session redirect behaviour. It was mentioned in the developer blog this week here: https://developers.facebook.com/blog/post/552/

The comment about it isn't very clear - I would guess they mean if there is no redirect_uri provided, then add this? Check what value you are getting in $_SERVER['REQUEST_URI']
