IE has trouble viewing the shortcut icon, favicon.ico. This issue is consistent in all IE versions that I tested, ranging from IE6 to IE9b2. I believe this issue is caused by the output filter on line 124 of .htaccess which reads:

AddOutputFilterByType DEFLATE text/xml application/xml text/x-component

A simple way to test IE's reading of the shortcut icon is to add the follow HTML snippet to a file in the same directory:

<img src="favicon.ico" />

I'm not sure how the lines you quoted would affect favicon.ico displaying properly. Could you give us an example of how you are using the boilerplate (link/code/details etc.) and specifically what the "trouble" is?

Well I can confirm that site isn't working in Internet Explorer 6-9 but I'm not sure why.

Here's some screenshots to clarify the issue for people who cannot (or prefer not to) load up IE.

Chromium:

IE6 (7, 8 and 9 are the same)

I'll investigate some more when I have the time.

changing mimetype of .ico files to "image/x-icon". Details follow:

While Wikipedia would lead you to be believe one thing...
http://en.wikipedia.org/wiki/ICO_(file_format)#MIME_type
... specifically that the vnd.microsoft.icon mime type is correct..

Well that's wrong.

It does work in the address bar, IE can also use an .ico file as an
<img src> in some cases. But it has to be served as image/x-icon
instead.

So thanks a lot wikipedia & jimmy wales' face. Psh.

They were reverted. :)

@davidmurdoch

Thats because I updated http://en.wikipedia.org/w/index.php?title=Favicon intead of the ICO one. Oops.

@davidmurdoch

Ok, NOW it is fixed. I hope the wiki nazi's don't revert it.
