Prevent image access...


I want to be able to prevent users from viewing images on my webserver (IIS6) using direct URLs e.g. should not be accesible.

Now, I have read about various methods to prevent hot-linking  etc etc.

One of which involves setting wildcard in IIS6 and redirecting every request to ASP.

However, I found that when I do this I cannot then redirect the user to the image after checking (referr check etc) because asp is handling it (loop scenario?).

Anyway, my set up is as follows:

1) I have a few web app directories which use images from my img (image) directory. The image directory is a virtual mapping to a folder on harddisk and it sits in the root along with web apps which need to access the images.

2) IIS version is 6 (upgrade I know, i know!)

I can think of two ways:

Is it possible to set up so that....

Any attempt to access would redirect to another page which checks for cookie, if cookie present then display image otherwise block.

thanks for your help.

Ah, never thought of removing the virual directory and reading from filestream. Hopefully this will not create any side-effects.
