IIS - Other - Help with folders

Hi all,

I need help with a problem I'm trying to solve.
I have a big image folder with 10,000 different folders, in every

folder I have files for different customers.

All the folders set on the same IIS (IIS 6).

Now I like to set for every folder a rule, that only users that enter

from uniqes domains can see folder number 10958.

For examples:
for domain: mydomain1.com,mydomain2.com,mydomain3.com users can see

folder number 165456
for domain: mydomain4.com,mydomain5.com,mydomain6.com users can see

folder number 543543

I find some solution:
* Set ISAPI REWRITE 3 (but I have a lot of problem with them and I'm

waitting them response. they don't response :-) ).
* Set web.config for every folder and check every HOST that enter the

folder (I don't find details about this option).


Can someone can help with this, maybe you have better idea or you can

expand my idea.

Thanks a lot,
Noam
