link sniffer Web Service: Error: Request format is unrecognized

Question

http://www.c-sharpcorner.com/Code/2003/March/LinkFetcher.asp I have been trying to get this to work and am getting an error message I am running into a problem both locally and when I try to post the service elsewhere. I am getting an error message The underlying connection was closed: The remote name could not be resolved. . Internet Explorer custom error Exception Details: System.InvalidOperationException: Request format is unrecognized. Netscape error reports This XML file does not appear to have any style information associated with it. The document tree is shown below. Also, it's unclear to me what the findVal text is for? I tried to contact the author and the mail address I tried was not functioning. thanks
