Another solution for cache problem in IE.

This solution was given by the member of the Google group ,so i think i should keep this in my blog for future reference for me and for every flex lover.So the lines are here..In IE

1) Go to internet options.

2) Temporary Internet Files >  Settings > Check for new versions ofstored pages >  Select Radio : “Every Visit to the server”then check your application.

It should work, and gets the new data. Itis the problem with Cache.This problem generally arises in AJAX also. Then we can’t expect everyuser to workaround these settings.

So add this header to the server side page.

———————-”Cache-Control: no-cache, must-revalidate”———————-

For example, in php

<?phpheader(”Cache-Control: no-cache, must-revalidate”);?>

This is the Permanent solution to cache.. comparing to the previous post
