Basically we're looking to figure out whether IIS can be configured  
to sent no content-type header at all. In particular, it would be  
worthwhile to determine what IIS sends by default when no filename  
extension can be determined  though I believe IIS also uses sniffing  
by default. So it would be best to place a file on the server that  
IIS had no way of sniffing and no way to determine the filename  
extension mapping.

Whatever information you can provide for us on this would be great.

1) what does IIS do in its default configuration when it cannot  
determine a file's type?
2) is there any way to change the configuration to send no content- 
type header at all when it cannot determine a file's type?
3) how is it configured by default to send content-type headers for  
files with no filename extension?
4) can one configure it to send a particular content-type header for  
files with no filename extension?

There is a wiki page on this, so you could add the results of these  
questions somewhere there (or reply here).

Take care,
