Hi,

I've been searching around for some time now and cannot find an answer to my
question.
I know that is possible to register more MIME types into a website, and even
a folder. But can you restrict mime types for one folder.

Example: I have a folder /test under www.somesite.com. From this folder I
would like to restrict GIF files from being downloaded. The best scenario
would be to only allow asp files to be parsed and nothing else. The purpose
is that I want to authenticate download of resources in a folder. I cannot
move the files due to design restrictions in another part of the system.
When a user uploads a file, lets say, Image.gif, an asp file is
automatically created with the namne Image.gif.asp that takes care of
authentication and creating the stream. The whole idea might be bad, thats
why I'm asking you guys.

Thanks
/Johan

You could create a Virtual Directory to the folder and set the MIME type
that way... it will work.

In addition to what other have said:

If you are afraid of "hot linking" stealing bandwidth from you, it would be
a nicer solution to have an ISAPI filter. One of the benefits is that it
will not execute an asp file every time someone downloads an image. ISAPI
filter should in general work faster.

Hi!

Thanks for your answer. It's more of a security reason, making sure people
don't steel images or documents.

Hi!

Thanks for your answer!

I can only find a place to add (allow) more MIME types on a folder or
virtual dir, how do I restrict a mime type?

Hi again!

Tested another thing. Removing the read permission from a folder seems to
block most types, but still allows ASP script to parse.

Any drawbacks using this "option"?
