How do I find out where a call to my webservice (.net asmx) came from?

From within a webmethod (.net asmx fi开发者_StackOverflowle) - is it possible to determine from where the call to the webmethod came?

Thank you

You have this :

httpContext.Current.Request.UserHostAddress

MSDN

To get this host IP adress. but if by where you mean a place, , you can't.
