Response.Redirect: Moving the User Around
Response.Redirect is kind of like a call forwarding button. It sends the user on to any location you designate.
The syntax is virtually the same as Response.Write. Instead of entering a word or phrase that you want to be sent to the browser, you enter the URL of the destination that you want the user to be redirected to. For example:
The code above will send the user on to the HTMLGoodies web site. You can also assign Response.Redirect a destination from a variable like this:
<% Option Explicit %>
<% Dim strDestination %>
<% strDestination = "http://www.HTMLGoodies.com" %>
<% Response.Redirect strDestination %>
So, why would I ever use this?
The most common usage for Response.Redirect is in processing user input. Let's say, for example, you have built an ASP application that allows you and your friends to exchange DVD's and keep track of them. One of your pages is a form that asks the user whether they want to add a DVD to the list, delete a DVD from the list, borrow a DVD or return a DVD. Once they have made a selection you can then send them off to the appropriate page by using Response.Redirect in cooperation with a Case statement.
There are, of course, other valuable uses for Response.Redirect, but the type of situation listed above is the most common.
