Read Session Id using Javascript

Question

Is it by any means possible to read the browser session id using javascript

User · Answer

you can probably ping the server via ajax inside javascript. The php file might look something like:

<?php
session_start();
$id = session_id();
echo $id;
?>

This will return you the current session id. Was this what you were looking for.

As far as I know  a browser session doesn t have an id   If you mean the server session  that is usually stored in a cookie  The cookie that ASP NET stores  for example  is named  ASP NET SessionId

User · Answer

you can receive the session id by issuing the following regular expression on document cookie   alert document cookie match  PHPSESSID             in my example the cookie name to store session id is PHPSESSID  php server   just replace the PHPSESSID with the cookie name that holds the session id   configurable by the web server

For PHP s PHPSESSID variable  this function works   function getPHPSessId         var phpSessionId   document cookie match  PHPSESSID  A-Za-z0-9     i        if phpSessionId    null           return          if typeof phpSessionId      undefined           return          if phpSessionId length  lt   0          return          phpSessionId   phpSessionId 0        var end   phpSessionId lastIndexOf           if end    -1  end   phpSessionId length       return phpSessionId substring 10  end

The following can be used to retrieve JSESSIONID   function getJSessionId        var jsId   document cookie match  JSESSIONID              if jsId    null            if  jsId instanceof Array              jsId   jsId 0  substring 11           else             jsId   jsId substring 11             return jsId

User · Answer

Yes  As the session ID is either transported over the URL  document location href  or via a cookie  document cookie   you could check both for the presence of a session ID

User · Answer

Here s a short and sweet JavaScript function to fetch the session ID   function session id         return  SESS w ID         i test document cookie    RegExp  1   false      Or if you prefer a variable  here s a simple one-liner   var session id    SESS w ID         i test document cookie    RegExp  1   false    Should match the session ID cookie for PHP  JSP   NET  and I suppose various other server-side processors as well
