IE request getting dropped in restore view Phase
we are having a richfaces(version 3.3.3) application and we are facing a issue with IE.The request to the server getting dropped sometimes.After enabling logs and what we got is like the request hangs after it try to restore the view.We get this only whenwe access the page thru a VPN connection and a slow network.It will hang in the restore phase and after a logn time it will jump to Render response phase.
Following is the log while we got the issue:

2011-08-31 05:19:36,971 [TP-Processor1] - decrypting w/ DES/ECB/PKCS5Padding
no progress after this.This issue is only in IE.
The client side log says that after request state 1 in hangs and when timedout will jump to request state 4.
So the problem is our customers might be in the middle of somethg and they need to logout and login again to continue and they will lose all the changes they made.
We tried modifying the response header to clear the cache in the filter since we thrght its a IE cache issue but it also didnt help:
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-store");
response.setDateHeader("Expires", -1);
Please help.thanks in advance.
