Dear Pushendra????
Try to upgrade your ASA IOS to 8.4.2 version and Update ASDM latest version. And also update CSC-SSM-20 IOS to 6.6.1125.0.
There you have support of HTTPS filtering.
Just go through the release notes of these IOSs for more information.
It is still bug in ASA CSC, which is not supports https filtering with Internet Explorer in Pre-Windows 2003 operating systems.
Later versions of Windows-2003 with browser internet explorer HTTPS filterting working fine.
In above both cases with Firefox browser HTTPS filtering fine.
Rate me if this post helpful..
