I am trying to export ics (calendar) file on ie 6. Althou I am able to save
and then
open it but I am not able to directly open it.

I am not facing this problem on ie 7.

My ics file looks like this: -

BEGIN:VCALENDAR
PRODID:-//Ben Fortuna//iCal4j 1.0//EN
VERSION:2.0
METHOD:PUBLISH
BEGIN:VEVENT
DTSTART;VALUE=DATE:20070929T090000
DTEND;VALUE=DATE:20070929T180000
CREATED;VALUE=DATE:20070921T085512
DTSTAMP;VALUE=DATE:20070925T062051
DESCRIPTION:Category
SUMMARY:Mohana
LOCATION:Delhi
UID:217
CONTACT:nobody@vodafone.co.uk
END:VEVENT
END:VCALENDAR

In my java code, I am adding the following header: -

           response.setContentType("text/calendar");
           response.setHeader("Filename", fileName);
           response.setHeader("Content-Disposition", "attachment;filename="
+fileName );          
           response.setHeader("Cache-Control", "public");

Any pointers ?
