How to serve files from IIS 6 on Windows Server 2003?

Question

I have files with extensions like ".dae" , ".gtc" , etc. When I try to hit these files over http, the server returns a 404, but they are in the directories. However I can serve readily known file extensions; if i just rename them to say, xml, they are accessible.

Any suggestions for what the problem may be?

Answer 1

If you request a file with an extension that is not a defined MIME type on your IIS 6.0 Web server , you receive a " HTTP Error 404 - File or directory not found " error message.

To define a MIME type for a specific extension (.dae in your case), follow these steps:

• Open the IIS Microsoft Management Console (MMC), right-click the local computer name , and then click Properties .
• Click MIME Types .
• Click New .
• In the Extension box, type the file name extension that you want (in your case .dae ).
• In the MIME Type box , type application/octet-stream .
• Apply the new settings.

Note: you must restart the World Wide Web Publishing Service or wait for the worker process to recycle for the changes to take effect.

Answer 2

You need to define additional MIME types on IIS 6 for the extensions that you mentioned.

Here is the MS article on how to add additional MIME types to IIS6:
