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
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 https://www.askapache.com after 0 seconds.
Redirect with javascript
These go in the
section of your html.
Basic javascript Redirect method
Will redirect user to https://www.askapache.com immediately
Redirect after specific time period
This will redirect to https://www.askapache.com after 2 seconds
Redirect with PHP
Using "Location" header
Using "Refresh" header
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

Redirect with Python / Django
Thanks to thebjorn for contributing this first one, which issues a 302 Redirect.
from django import http def view(request): return http.HttpResponseRedirect('https://www.askapache.com/')
This example was contributed by John and shows how to issue a proper 301 Redirect, additional info on this below the example.
from django import http def view(request): return http.HttpResponsePermanentRedirect ('https://www.askapache.com/')
Django includes a number of HttpResponse subclasses that handle different types of HTTP responses. Like HttpResponse, these subclasses live in django.http.
- HttpResponseRedirect
- The constructor takes a single argument -- the path to redirect to. This can be a fully qualified URL (e.g. 'https://www.askapache.com/htaccess/') or an absolute URL with no domain (e.g. '/htaccess/'). Note that this returns an HTTP status code 302.
- HttpResponsePermanentRedirect
- Like HttpResponseRedirect, but it returns a permanent redirect (HTTP status code 301) instead of a "found" redirect (status code 302).
- HttpResponseNotModified
- The constructor doesn't take any arguments. Use this to designate that a page hasn't been modified since the user's last request (status code 304).
