IIS & ASP.NET blocking file

Question

Hi

I have an ASP.NET app running in IIS that is hosting files all great but it blocks all *.upd files and says http 404.

If I turn directory listing on it lists the file just great but I cant download it any way...

Is there any way to fix this?

Answer 1

You have to configure IIS to serve your file type as it won't serve unknown ones: http://support.microsoft.com/kb/326965

Answer 2

You need to add the .upd file type to the IIS Mime Types. You can do this through:

• Launch IIS MMC
• Right Click -> Properties on machine name node
• Click Mime Types button
• Click 'New'
• Enter the 'Extension' (in this case .upd')
• Enter the Mime Type (you need to find out the type, if you're not sure try application/octet-stream, it's always a good bet).
• Click OK and close all dialogues.

The file should then be downloadable.
