Read Session Id using Javascript
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.
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;}
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)
