301 Redirect Cheatsheet

I got tired of always having to search google to remember the syntax for issuing seo friendly (300, 301, 302, 303, 305, 306, 307) Redirects using multiple programming languages and methods… so I made my own list!

Redirection Methods

Am I missing something? Most definately! Please use the comment form below to suggest new code.

Redirect with meta http-equiv tags

These go in the <head> </head> section of your html. Usually when you use this meta redirect method you should also use the javascript method, just to be safe.

Refresh meta http-equiv tag

Redirects to http://www.askapache.com after 0 seconds.

<meta http-equiv="refresh" content="0;url=http://www.askapache.com" />

Redirect with javascript

These go in the <head> </head> section of your html.

Basic javascript Redirect method

Will redirect user to http://www.askapache.com immediately

<script type="text/javascript">
window.location.href='http://www.askapache.com';
</script>

Redirect after specific time period

This will redirect to http://www.askapache.com after 2 seconds

<body onload="javascript:setTimeout(function(){window.location.href='http://www.askapache.com'},2000);">

Redirect with PHP

Using “Location” header

<?php
header('Location:http://www.askapache.com');
exit;
exit();
?>

Using “Refresh” header

<?php
header('Refresh: 0; URL=http://www.askapache.com');
exit;
exit();
?>

Ultimate PHP method

It redirects to a page specified by “$url”. $mode can be:

  • LOCATION: Redirect via Header “Location”
  • REFRESH: Redirect via Header “Refresh”
  • META: Redirect via HTML META tag
  • JS: Redirect via JavaScript command
<?php
function do_redirect($url,$mode)
{
    if (strncmp('http:',$url,5) && strncmp('https:',$url,6)) {
        $starturl = ($_SERVER["HTTPS"] == 'on' ? 'https' : 'http') . '://'.
        (empty($_SERVER['HTTP_HOST'])? $_SERVER['SERVER_NAME'] : $_SERVER['HTTP_HOST']);
        if ($url[0] != '/') $starturl .= dirname($_SERVER['PHP_SELF']).'/';
        $url = "$starturl$url";
    }
    switch($mode) {
        case 'LOCATION':
        header("Location: $url");
        exit;
        case 'REFRESH':
        header("Refresh: 0; URL=\"$url\"");
        exit;
        case 'META':
        exit;
        default:
        ?><script type="text/javascript">
        window.location.href='<?=$url?>';
        </script><?
    }
    exit;
}
?>

Redirect with Perl

Simple 302 Redirect with perl

#!/usr/bin/perl
my $URL = "http://www.askapache.com";
print "Status: 302 Moved\nLocation: $URL\n\n";

Simpler 302 Redirect with perl

#!/usr/bin/perl
print "Location: http://www.askapache.com\n\n";
exit;

Redirect with ColdFusion (CFM)

Using cheader for 301 “permanent” redirect

<cfheader statuscode="301" statustext="Moved Permanently">
<cfheader name="Location" value="http://www.askapache.com">
<cfabort>

Using clflocation for 302 “temporary” redirect

<cflocation url="http://www.askapache.com">

Redirect with ASP (VB Script)

301 Redirect

<%@ Language=VBScript %>
<%
response.status="301 moved permanently"
Response.AddHeader "Location", "http://www.askapache.com"
%>

Redirect with shell script

302 Redirect with sh shell script

#!/bin/sh
echo "Content-type: text/html"
echo "Location: http://www.askapache.com";
echo "";
exit 0;

  1. Luis ~

    Which would be the preferred redirect method: PHP or Mod Rewrite ? Why?
    I’m just curious abut it.

  2. Natasha ~

    This is great information. Thanks a bunch

  3. David Simmons ~

    Excellent collection! Thx

  4. nBridges Media ~

    Thanks for such nice list

  5. thebjorn ~

    Thanks for the list! saved me a bunch of time. If you’d like to add the code for Django/Python it is:

    from django import http
    def view(request):
    return http.HttpResponseRedirect(‘http://www.htaccesselite.com’)

  6. AskApache ~

    @ Ash

    Thanks! I will have to go through and clean up the code, especially adding code to do 307 Temporary Redirects, which should almost always be used instead of a 302 Redirect.

  7. Ash Nallawalla ~

    Thanks for this fantastic checklist! I will send my students to this page.


It's very simple - you read the protocol and write the code. -Bill Joy
