General 301 Redirection on Apache Server

General 301 redirection on Apache server using the .htaccess file.

Using the .htaccess file you can:

Redirect an entire site to a new domain (all urls to be matched on the new domain). Put this directive in the .htaccess file in the root folder of the OLD site:
```
Redirect 301 / http://www.example.com/
```
Redirect an entire site to the homepage of the new domain. Put this directive in the .htaccess file in the root folder of the OLD site:
```
RewriteEngine On
RewriteRule ^(.*)$ http://www.example.com/ [R=301,L]
```
Redirect a particular page url to a new url on same or new domain.
NB: put this directive in the .htaccess file in the root folder of the OLD site if moving to new domain:
```
Redirect 301 /old-url http://www.example.com/new-url
```
Pay attention to trailing slashes if moving folder-type urls.
Change the type of extension for every page, with no other changes.
– E.g. changing all pages from *.html to *.php :
```
RedirectMatch 301 (.*)\.html$ http://www.example.com$1.php
```
– E.g. changing all pages from *.asp to *.php :
```
RedirectMatch 301 (.*)\.asp$ http://www.example.com$1.php
```
