MIME types IIS

[jadams]

So I'm setting up an http redirect for some game server using my IIS web server.

Specifically for UT3 there are .upk, and .ut3 files that will be downloaded by the client. I added: .* .UT3, and .UPK as mime types on the site. Though I still get 404's when i enter the address. The directory listing works and I click on the file and it says the same thing.

Pictures work. Text files work. Other "known" extensions work. What am I doing wrong?

Thanks.

EDIT - even checked the web.config and they're in there.

Sounds like the extensions of "UT3" and "UPK" have been defined, but what value did you put in the "MIME type" field?

What version of IIS is this? Or, better yet, what version of Windows Server?

Edit: Have you tried a MIME type of "application/octet-stream"?

IIS 7 on Server 2008 R2.

Tried changing to that MIME type and same result.
