Overview

Sometimes it is required to redirect a User visiting the website.
A redirect changes the URL in the browser from one URL to another.

There are various methods on how to accomplish this.

Redirects Using .htaccess

A simple way to redirect is to use htaccess. 
For a more general .htaccess guide visit the Knowledgebase.

Example 1: Redirect to web.example.com

In this simple example, we just redirect the Clients Web-Browser.

RewriteEngine On
RewriteRule ^ http://web.example.com [R=301,L]

Example 1: Redirecting from www.example.com

In this example we simply redirect a Client when the 
URL is www.example.com to example.com.

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule ^(.*)$ http://example.com/$1 [R,L]

Example 2: Redirect to SSL

The following directives check for a variable called HTTPS that gets
set whenever SSL is used. If this is not set (non-ssl connection), the 
client gets Redirected to SSL (https) for the same Hostname + URL path.

RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} !^on$
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R,L]

Notes on Redirects using .htaccess

An optional number may be added onto a R flag to specify a redirect code. By default a 302 is sent in a redirect response. (use R=XXX, where XXX is the response Code. Example: R=307).

Redirect using PHP

Sometimes a quick redirect from a directory (via index.php) or php script is required,
In this example we redirect browser accesing this php script to www.example.com

<?php
header("Location: http://www.example.com/"); /* Redirect browser */
?>
