Change URL on click of browser refresh button

I have a login.aspx page. There is a validation in another page say FirstPage.aspx once login successful, and if the validation fails,page will be redirected back to "login.aspx?status=false". Then the error message is assigned a label in Login.aspx page and it will be displayed. Now, the requirement is, if I click on browser's refresh button now, teh URL should get changed to "login.aspx".

How to achieve this. Any help is greatly appreciated.

Thanks in advance

You can kind of do this (detect a page refresh) in a couple of way - see Detecting Page Refreshes :: Using JavaScript on Client-Side.

The simplest approach seems to be to use hidden form variables. Apparently form variables are maintained across page refreshes by most modern browsers, by updating the value of a hidden field with JavaScript we can take advantage of this to detect when the page is refreshed:

<input type="hidden" name="visited" value="" />

if( document.refreshForm.visited.value == "") {
    // This is a fresh page load
    document.refreshForm.visited.value = "1";
} else {
    // This is a page refresh
    // either redirect to login.aspx, or just update the page accordingly
}

You can either redirect the user when you detect a page refresh, or better would be to alter the appearance of the page accordingly (which prevents an extra refresh of the page)
