Redirecting and Logging off.

Hi,

I need guidance regarding two problems/concepts:
1)Which is the best way to handle log-in and log-out functions in ASP?

2)Further, I have kept one button in asp page, now when user clicks on it, it should send user to the page from which it was accessed, mean to the referrer page.
Coding is in VBScript and ASP.

Rupen,

1) Can you explain that in detail on what you are looking for regarding login/logout.

2) You can get that using the following.

Code:

<a href = "<%=Request.ServerVariables("HTTP_REFERER")%>">Click here to go back</a>

I am developing timesheet application for our employee, so for entering their time they will log in using their IDs, after entering time they need to log off, meaning that they should not be able to go back (using browser button) and enter time or view reports etc..

For (2)where should i write this code in click event of button?? Please explain it.

If you are looking for restricting the user from going back after logging off, better use

Code:

onload="javascript:history.go(1)"

in the <Body> tag on the page from where the user logs out. This will not let the user go back once logged out. This has to be given on all pages from where logoff is provided.

Also use session variable and check on all pages if the session variable contains value, carry this out till the user signs off. Once the user signs out, Use

Code:

Session.Abandon()

that clears the session variables and thus if the user is still able to go back, then automatically he wouldn't be able to access the pages, as the session is abandoned. You got to be careful to check the session values on all pages, which fall under log on session for the user, and redirect the user to a customized error page, if the session is invalid.
Hope that helps.
