SSL for in IE7 prohibited for css?

[MattyUK]

Hi

I've an odd problem to invite comment on.

I have a page loading via an SSL connection.
[example.com...]

Within the page all supporting images, css and js files are loaded via https so as to avoid the mixed content problems and warnings.
i.e:

<link href="https://www.example.com/thecss.css" rel="stylesheet" type="text/css" />

Now when testing this page I get the following:
Firefox 2.0 says page is fully encrypted with no problems or warnings.
IE7 prompts to load unsecured items.

On further checking I directly accessed the css file via url.
[example.com...]
In Firefox 2.0, there was no problem.
With IE7 it states the requested site is not available and it cannot download the CSS file.

The server and file is present in ssl mode since Firefox loads it.

If I change the url to normal http:
http://www.example.com/thecss.css

The file loads in IE7 and Firefox 2.0.

What could be the problem? A bug in IE7? Missing mime types on the server?

Resolved.

I honestly can't say how. A server restart didn't help but a modem disconnect/reconnect with different IP did. I wonder if a transparent forced proxy could have been getting in the way? I also reset IE settings at the time but no change was noted until after the full restart for a new IP, so it is feasible it was something in the IE7 security settings. No matter it's working now.
