Cookie Redirect 2

William Bontrager Jan 31, 2007

General

When a page has performed it's purpose, a cookie can be set to redirect the browser to a different page on subsequent visits. Easily implemented.

(Because it will redirect after one visit, the example is not shown on this site.)

// Three items can be customized (values between quotation marks):
//
// 1. What URL shall the browser be redirected 
//    to if a cookie was previously set?

var RedirectURL = "http://shamar.org";

// 2. How many days shall the cookie live in 
//    the visitor's browser (0 means remove 
//    cookie whenever browser closes)?

var DaysToLive = "365";

// 3. What name shall the cookie have (any 
//    sequence of alphabetical characters 
//    is okay, so long as the name doesn't 
//    conflict with any other cookies that 
//    this web page might be setting.)?

var CookieName = "HasVisited";

// No other customization is required.
