Question

I have a JSON-based WS for my website and I get a non-stop requests by Google Bot to my ASMX file.

How can I stop these requests?

Note: I tried reading about it here, but it doesn’t seem to supply any elegant solution for WS.

Here is the exception I get /w HTTP request:

Logged date (UTC):  20/02/2011 12:00:59
Requested URL:      https://dynamic-subdomain.somedomain.com/ExternalApi/Rest/RateServices.asmx/GetRate

A general error has occured.

Exception:
