| Web site redirection methods: |
| |
|
| 1 |
One can forward a web page URL or home page using the following web page with the "Refresh" directive: |
| |
<META HTTP-EQUIV="Refresh" Content="0; URL=http://www.company.com/dir1/"> |
| 2 |
# Use a CGI script to forward a home page: (mod_cgi)
File: httpd.conf |
| |
ScriptAlias / /var/www/cgi-bin/redirect-script/ |
| |
File: /var/www/cgi-bin/redirect-script |
| |
#!/usr/bin/perl
print "Status: 301 Moved\r\n" .
"Location: http://www.new-domain.com/\r\n" .
"\r\n";
|
| 3 |
Use Apache module (mod_rewrite)
File: httpd.conf |
| |
RewriteEngine On
RewriteRule /.* http://www.new-domain.com/ [R] |
| |
Forwards all references in entire domain. |
| 4 |
Use Apache module (mod_alias )
File: httpd.conf
Redirect Domain: |
| |
Redirect / http://www.new-domain.com/ |
| |
Redirect Page: |
| |
Redirect /web-page.html http://www.new-domain.com/destination-web-page.html |
| |
Note: Redirect directives take precedence over Alias and ScriptAlias directives. |
| 5 |
Apache 301 redirect using the .htacess file: |
| |
If one wants to permanently forward an entire web site to a new URL or forward a single page permanently and have the search engines update their database, one should use a 301 redirect. This may redirect to a new server or to inself but to a different domain. This tutorial shows how. This method is a variation of using the mod_alias redirection shown above except that it allows the customer to redirect themselves by providing a .htacess file themselves. |
| |
File: .htaccess Create a file /home/domain/.htaccess in that directory of the domain to be forwarded that looks something like this: |
| |
Redirect entire domain: |
| |
Redirect 301 / http://www.new-domain.com/ |
| |
Note: The use of the "/" at the end of the redirected domain. This is necessary so that http://www.old-domain.com/page1.html will be redirected to http://www.new-domain.com/page1.html.
OR
Redirect specified pages: |
| |
Redirect 301 /old-page-1.html http://www.newdomain.com/new-page-1.html
Redirect 301 /old-page-2.html http://www.newdomain.com/new-page-2.html |
| |
You may use the following directives:
- 301: permanent
- 302: temp
- 303: seeother
- 410: gone
For example: |
| |
Redirect permanent / http://www.newdomain.com/ |
| |
If an incorrect directive is used in the httpd.conf or .htaccess file it will result in a server error. Check your log files: /var/log/httpd/error_log. |
