Setting up a 301 Redirect in IIS 6.0

If you are planning to move a website to a new domain name, the most efficient way to setup URL redirection is to with the 301 Redirect. The 301 HTTP status code means moved permanently. For this reason, it is the best method to use to preserve a website’s search engine placement.

This tutorial will cover how to completely (including query strings) redirect a url. Setting up search engine friendly 301 Redirect for a web application in Microsoft IIS 6.0 is a matter of a few settings.

  1. In your IIS properties window, you will want to click Redirect to a URL radio button.
  2. Next, in the box below, you will want to input the new URL address. At the end of the new URL address, you want to append $S$Q to preserve the querystrings. Therefore, if I want to redirect to http://www.victorchen.info/test.php?index=1, the string will be http://www.victorchen.info/$S$Q.
  3. Finally, check the checkbox A Permenant Redirection for this resource.
  4. Click Apply and Close

How to Redirect Users to a Different Page in C#

March 31st, 2008 3 Comments

Redirecting a web user to another web page without requiring the user to click a link is a common practice in web development. The built in function of C# is the Redirect function. The redirection function can take one or two input parameters. With one input parameter, simply specify the redirect url.

Response.Redirect("http://www.victorchen.info");

By using only one parameter, code after the Redirect function can still be executed. To prevent this, use the overloaded Redirect function with two input parameters. The first input parameter is still the redirect url, but the second input is the a boolean variable indicating whether remaining code on the page should continue executing or stop when the redirection function is reached.

Response.Redirect("http://www.victorchen.info", false);

Redirect is a function of the HttpResponse class. The Redirect function returns void.

How to Automatically Redirect a Page in PHP

March 27th, 2008 3 Comments

To redirect a page to another page during PHP processing, simply use the header function demonstrated below:

<?php
   header("Location: http://www.victorchen.info");
?>

Whenever this script is reached, the page will automatically redirect to http://www.victorchen.info.

  1. The header function must occur before any page output. This includes page outputs originating from include() or require() functions. Additionally, keep an eye out for blank lines before the header function is executed.
  2. The URL does not need to be a full url (http://www.victorchen.info). It can alternatively be “../index.html”.

The below example will not work because there is an output of “This will not work” before the header() function is called.

<?php
   header("Location: http://www.victorchen.info");
?>

This example will also not work because the text “This will not work” is placed in an php echo command.

<?php
   echo "This will not work";
   header("Location: http://www.victorchen.info");
?>

This next example shows how having a hidden space before the first php command will also not work. Please note the first line of the example below is empty! To see this highlight the code below and see the first character is a blank!

<?php
   header("Location: http://www.victorchen.info");
?>

Lastly, the following code below will work. The string “This will work” is placed after the redirect.

<?php
   header("Location: http://www.victorchen.info");
   echo "This will work";
?>

Please note that the string “This will work” will never actually execute in this scenario, as the header function will trigger the page to first redirect. Simply placing an if statement around the header function allows toggling of when the header function is executed.
