In my inaugural post, I described a problem I had with a WebMethod erroring out instantly on the client, accompanied by a puzzling message in the Event Log, regarding viewstate.
On a whim, on that site, I decided to “publish” the website from within VS 2005 to a separate directory. I set up another virtual directory within IIS to point to that directory, loaded up the site and IE, and all my WebMethod calls were working!
From IE6, that is.
From FireFox, none of the calls work on the published website....
...the first time. If I click on the link that calls the WebMethod again (after getting the instant error), it works fine. Very weird.
