I have a Forms secured site where I decided to rename the classic login.aspx to default.aspx, and now the login does not react to input unless I browse to /default.aspx. Browsing to justhttps://domain.tld/ and entering credentials causes the page to reload with no authentication messages. Has anyone else encountered this issue (I am using .Net 4.5 on IIS 8) or know what causes it and why. I am going to add a redirect from / to /default.aspx for the time being, it just seems quite an odd issue.
Edit: Where I said reload blank, I did not mean no data, I meant reload as if I was requesting it for the first time, having forgotten the details I'd entered and returning no error message or triggering any login events.
