SSL Form Post between IE6 and Apache 2.2 fails (This page cannot be displayed).
The Cry for HELP:
Any assistance and insight you can bring to my situation would be greatly appreciated. I've spent over 12 hours troubleshooting. I've also enlisted the help of a peer who spent over 8 hours on the issue. We were unable to come up with a solution on our own.
The Scenario:
I am attempting to post form data including a file over SSL on IE 6.0 client served by Apache version 2.2 server. The post fails with "This page cannot be displayed" error. (see simplified form below) The php code works fine on all three browser versions on the "Old Server" environment. However, on the "New Server" environment it fails on IE6.
The Theory:
This code works perfectly on IE6, IE7 or Firefox 2.0 with apache 2.0. Further, this code works perfectly on IE7 and Firefox 2.0 with apache 2.2. It only fails with the combination of IE6 and apache 2.2 which makes me think it's not a php.ini or apache configuration issue. I suspect there is some incompatibility with the SSL handshake between Apache 2.2 and IE 6. Another thought is that it might have something to do with mod_rewrite which is enabled on the "New Server" environment and not enabled on the "Old Server" environment.

Windows XP Home

FreeBSD 6.1

Are there any messages in the webserver log for ssl or non SSL if you acces the page?
ASKER
Keeping in mind that this form posts to itself, there are no messages in the access_log or error_log when I click on the submit button to POST the form. There is, of course, an entry in the access_log when the form initially loads (before submit).
First the form is typical called via GET then filled out and submited via POST-Method to the server. So there must be two entries in access_log, First get and then POST. So if there is no second entry in the access log the form is not posted back to the server.
ASKER
Ok, on that we are agreed. The form is not posted back to the server. Oddly, this only happens on IE6 over SSL. I can access the same form on IE6 with no SSL and it works perfectly.
Also I should mention the following update when posting over SSL:
Step 1: Load Form
Step 2: Enter text & browse for file.
Step 3: Click Submit
Response: Page Could Not Be Displayed
Step 4: Click Back
Step 5: Enter text & browse for file.
Step 6: Click Submit
Response: For submits!
My Thoughts: It seems pretty strange that I can submit the form, get an error, go back, fill out the form exactly the same way, submit it again, and THEN it will post. The response is consistant even after restarting the browser, restarting computer, etc. The post goes through the second time after clicking on browser's back button.
