I always thougth the url
http://server/_vti_bin/Lists.asmx is open ie. dont need authentication.
But recently i installed sharepoint server 2010 in one of my clients machine and put it on public. But when i hit the URL in the browser i demanded authentication.
This this is causing problem in my middleware code. Could some one tell me what actually it is.
Is it demanding sharepoint authentication or IIS or something else?
