Hi Arka, HTTP is a somewhat stateless protocol, so in general the post->template->post round trip is perfectly safe.
As far as I can tell, you seem to be doing things just fine. Does the error show up without SSL? Does it show up in non-IE browsers? You do not, perchance, have any load-balancers in the equation do you? They can sometimes screw up SSL sessions. Is there any more detail in the error message than "The Page Cannot Be Displayed"? Is it an IE error or IE reporting a server-side error? Does anything show up in the server logs?
