ShopSite and .net?

[KONSTANTIN VASSILEV]

Are there successfull integrations with
ShopSite7 and .net application?

I wrote a shipping add-on. The add-on accepts parameters
from the CGI environment, then passes a request to
http:// based web service located on my server and returns
the parameters back to ShopSite.
It's written on managed C++ in order to be able to accept
CGI POST parameters from the environment.

What is going wrong:
I receive "file not found" error attepting to access the .asmx
file containing the web service. The web service is located
at http://... web address.

The program is running just perfect from command line or when
called from .html.

When embedded in ShopSite I receive this error.
Would you help me to resolve this error? Obvioulsy it's in
ShopSite because I receive this error only when called
from ShopSite.

Thnaks in advance,

Konstantin
