How do i load or reload the same page on form post

I notice on some sites i can login wrong which brings me to a login page. log in incorrectly again which brings me to a wrong password page (where i can log in) and if i login wrong again i dont increase my page history count. It takes exactly 2 backs no matter how many times i get it wrong and i dont see any pages in my f开发者_如何转开发orward history

How do i do that? ASP.NET

Take a look at this:

Server.Transfer Vs. Response.Redirect

Basically, if you want to do it without the user (browser) knowing about it, you use Server.Transfer; otherwise you do a Response.Redirect.

Also note, although not in server side code, there is a possibility the site uses Javascript like location.replace() - this way the history does not change.

You dont. As long as the login url stays the same there wont be another page added to the history. There may be parameters after the ? that changes the url or possibly POST data.
