Chris, Thank you kindly for your response.

It is actually post->template->post->template Not sure if that makes a difference though. Also it is not clear to me how it being a stateless protocol implies that the round trip is OK. I am a newbie though, so don't worry about explaining the whole background unless it can be reduced to a one-liner. :-) > As far as I can tell, you seem to be doing things just fine.

The error does NOT show up if I do not use SSL. Also, it does NOT show up in Firefox, with or without SSL. I also gave it a spin on Opera using SSL and it worked fine. So just the combination of SSL on IE, so far. What are load-balancers? I just mailed the hosting company asking if they use load-balancers just so I can get a yes or no, which I will mail here later. > error? Does anything show up in the server logs? This is bizzare, but the hosting company says on their support page that they no longer provide error logs. I will call them tomorrow and ask about it. > 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? The error message is the pretty familiar IE "The page cannot be displayed" error page. Right-clicking the page and checking the properties, the URL is as follows: res://C:\WINDOWS\system32\shdoclc.dll/dnserror.htm#https://ssl.somedomain.com/forms/Scripts/SubmitData.cgi The title in IE's title bar is Cannot find server. I am not sure if this is an IE error or IE reporting a server-side error. It is a very normal-looking IE error page, that most people are probably familiar with but never read in detail (myself included!). Here is the entire message on the page, bounded by the lines of asterisks. ******************* The page cannot be displayed The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings. -------------------------------------------------------------------------------- Please try the following: Click the Refresh button, or try again later. If you typed the page address in the Address bar, make sure that it is spelled correctly. To check your connection settings, click the Tools menu, and then click Internet Options. On the Connections tab, click Settings. The settings should match those provided by your local area network (LAN) administrator or Internet service provider (ISP). See if your Internet connection settings are being detected. You can set Microsoft Windows to examine your network and automatically discover network connection settings (if your network administrator has enabled this setting). Click the Tools menu, and then click Internet Options. On the Connections tab, click LAN Settings. Select Automatically detect settings, and then click OK. Some sites require 128-bit connection security. Click the Help menu and then click About Internet Explorer to determine what strength security you have installed. If you are trying to reach a secure site, make sure your Security settings can support it. Click the Tools menu, and then click Internet Options. On the Advanced tab, scroll to the Security section and check settings for SSL 2.0, SSL 3.0, TLS 1.0, PCT 1.0. Click the Back button to try another link. Cannot find server or DNS Error Internet Explorer ******************* Thanks again, any advice is appreciated!
