IE9 res://ieframe.dll Error

Question

I have a website that allows users to post images to Facebook pages. Im using a form and posting it to a hidden IFRAME, to prevent the user from being redirected after the images was posted.

The form definition:

<form name="myform" id="myform" enctype="multipart/form-data" action="" method="POST" onsubmit="getAction(this);" target="uploader">
//....form code....//

The Iframe:

<iframe name="uploader" width=2px height=2px style="visibility: hidden"></iframe>

My problem is, that in My Own Internet Explorer 9, When I'm trying to upload an image, Im getting these errors:

SEC7111: HTTPS security is compromised by res://ieframe.dll/dnserrordiagoff.htm 
SEC7111: HTTPS security is compromised by res://ieframe.dll/ErrorPageTemplate.css 
SEC7111: HTTPS security is compromised by res://ieframe.dll/errorPageStrings.js

And it gets even weirder, as in my friend's computer, which has the same IE9 version, and is connected to the same network, the post is working just fine (It is also working on another computer in my house, and another one in my brother's computer). I could have said that it is only a local problem, but as this site addresses many clients, I cant afford not understanding this error, if it happened on my own OS, it can happen on other machines.

I will also note that this is working on Chrome and FireFox with no problem.

I'm not sure that it is a code related issue, I've tried to google it and found both Microsoft Article and This article. But I removed any third party IE addons, We and my friends are connected to the same router (So it is not a router issue) and I've installed the latest Windows Updates.

I'm currently have no idea about solving the problem, So I wanted to ask if any of you have experienced similar/same errors ? and maybe has some ideas about solutions...

I will be happy to provide more code if requested, but I didn't want to fill the question with code from the first place, as in most scenarios it works fine.

Thanks.

Answer 1

It is best to fix this problem at server level rather than client side, since we can't expect all other site visitors to change their IE settings just so they can use your website.

As you mentioned, it is indeed caused by your iframe in https environment. IE9 is particular strict on this, so you will need to define it in your x-frame-options:

For Apache, HTTP Server

Add/Change following line in Apache Web Server’s httpd.conf file

Header always append X-Frame-Options SAMEORIGIN

Make sure it is not set to DENY. Restart web server

Let me know if that helps

Answer 2

If it is working in your friend’s IE 9, but not in your’s – then compare your security settings.

Especially the one named “Launching programs and files in an IFRAME” could be the deal breaker, I’d suspect.

If that one is not it, then try to set every security option offering this from “Disable” to “Prompt”, and see if you get any messages in your IE.
