I was wondering if anyone knows how to stop hotlinkers in
a way that is similar to .htaccess for Apache, but in
IIS5.0. Any help is appreciated.

Thanks

Found this recently, but I haven't given it a run yet:

If anyone knows more about this thingie, great :)

I got round the problem by storing the data (in my case the data was images) in a SQL database. One way of solving the problem... what is it you need to stop people hotlinking to??

Hey thanks for sharing...That links does work. Installed it.

But it pops up auth instead of replacing with a broken image like apache.

Oh well, at least it does what it's supposed to do: stop hotlinking.
I'm glad to know that :)

There are a few ASP utilities that deny access to anyone who hasnt visited your site(s).

(Can't recall the exact URL, but it was a link off of www.asp101.com.)

Also, you could use one of the various URL rewriting utilities (the IIS equivalent of Mod_Rewrite) that are around.
