I was wondering if youve recently logged into a site but accidently put the wrong password in? Could you NOT tell me if the error page went to a

Invalid username/password
//(this is the user field)
//(this is the pass field)

but DO tell me if the page went to a "cannot connect to server" page with the various methods of fixing the "cannot connect to server" problem.

P.S. This is for educational purposes only, and please PM me the site before telling the admin of the possible vulnerability.
the obvious reason for not posting the site, if everyone goes and tries to inject the site, then that sites owner aint gonna be happy.
