logout on browser close

[Jignesh <jignesh@icare.com>]

We have been struggling to handle logout on browser or tab close. 

We checked our apache ssl_log and found following.

On actual logout:

On tab close: 
======== 
 
115.112.67.33 - - [31/Jan/2014:07:20:23 -0500] "POST /hitinsiderEHRWeb/rest/logout HTTP/1.1" 202 58

On browser: 
======== 
 
115.112.67.33 - - [31/Jan/2014:07:24:05 -0500] "POST /hitinsiderEHRWeb/rest/logout HTTP/1.1" 202 58 
115.112.67.33 - - [31/Jan/2014:07:24:05 -0500] "GET /hitinsider_logout.php?callback=undefined&_=1391170952973 HTTP/1.1" 302 565 
115.112.67.33 - - [31/Jan/2014:07:24:06 -0500] "GET /hitinsider.php HTTP/1.1" 302 1829 

It seems to generate 302 message we have to open another empty window and from there we have to call 

hitinsider_logout.php to do further processing.

Any suggestion on this topic?
