title: How to use facebook restserver.php
body: <p>Well, I need to use rest api (api.facebook.com/restserver.php) of facebook but I never used this authentication method, I just used oauth with access_token. </p>
  
  <p>Someone could help me?</p>
  
  <p>I do not know how to get the parameters session_key and sig.</p>
  
  <p>I need something like this:</p>
  
  <p><a href="http://api.facebook.com/restserver.php?api_key=myapikey&amp;format=XML&amp;method=facebook.fql.query&amp;query=SELECT" rel="nofollow">http://api.facebook.com/restserver.php?api_key=myapikey&amp;format=XML&amp;method=facebook.fql.query&amp;query=SELECT</a> id,name,first_name,last_name FROM user WHERE uid=my_uid&amp;session_key=?????&amp;sig=??????&amp;v=1.0</p>
  
  <p>I need to use restserver.php with session_key and sig, but I dont know how get it.
