Apache Web Server Configuration for Web Site Redirection

上一篇 / 下一篇 2008-02-25 11:03:24

List of methods used to redirect a web site using Apache:

Web site forwarding and redirection methods:

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/">

This commands the browser to refresh the page with the new specified URL. This forwards a single page only and not the entire domain. It can forward the default home page for the domain giving the appearance of forwarding the domain..

or:

<html>
<head>
<META. HTTP-EQUIV="Refresh" Content="3; URL=http://www.company.com/dir1/">
</head>
<body>
This page will forward to http://www.company.com/dir1/ in three seconds.
<p>
Please update your links.
</body>
</html>

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";

Use Apache module (mod_rewrite)
File:httpd.conf
RewriteEngine On
RewriteRule /.* http://www.new-domain.com/ [R]
Forwards all references in entire domain.

Use Apache module (mod_alias)

File:httpd.conf

Redirect Domain:

Redirect / http://www.new-domain.com/

Redirect permanent / http://www.new-domain.com/

Redirect Page:

Redirect /web-page.htmlhttp://www.new-domain.com/destination-web-page.html

Note:

Redirect directives take precedence over Alias and ScriptAlias directives.
Other "Redirect" options include:temp(error 302) default - temporary redirect status,seeother(error 303) resource has been replaced andgone(error 410) resource has been permanently removed.

Examplehttpd.confwith virtual hosts for multiple domains which all redirect:

<VirtualHostXXX.XXX.XXX.XXX>
ServerName directtolinux.com
ServerAlias www.directtolinux.com
ServerAlias direct-to-linux.com
ServerAlias www.direct-to-linux.com
ServerAlias digitalpenguins.com
ServerAlias www.digitalpenguins.com
Redirect permanent / http://www.yolinux.com/
</VirtualHost>

Apache 301 redirect using the.htaccessfile:
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 itself but to a different domain. This tutorial shows how. This method is a variation of using themod_aliasredirection shown above except that it allows the customer to redirect themselves by providing a.htaccessfile themselves.
RewriteEngine on
RewriteCond %{HTTP_HOST} ^yolinux.com
RewriteRule ^(.*)$ http://www.yolinux.com/$1 [R=permanent,L]
This example forwardshttp://yolinux.comtohttp://www.yolinux.com/to unify your site to a single URL. See YoLinux.comcomments on why you may want to unify your web site to a single URL. This can also simplify your web logs if they can not distinguish between the two.

(Method 5) Apache configuration for redirect using httpd.conf and .htaccess:

This configures Apache to command the web browser to redirect by performing a GET from the "redirected" web site the user is being forwarded to.

File:/etc/httpd/conf/httpd.conf(older systems used access.conf)

Default:This disables the processing of.htaccessfiles for the system.

<Directory />
AllowOverride None
</Directory>

or for a specified directory:

<Directory/home/domain/public_html>
AllowOverride None
</Directory>

Specify directory containing site or page to be redirected:

<Directory /root-directory-of-web-site-to-be-redirected>
AllowOverride All
</Directory>

AllowOverride parameters: AuthConfig FileInfo Indexes Limits Options

File:.htaccessCreate a file/home/domain/public_html/.htaccessin 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 thathttp://www.old-domain.com/page1.htmlwill be redirected tohttp://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 thehttpd.confor.htaccessfile it will result in a server error. Check your log files:/var/log/httpd/error_log.

HTTP 1.1 Redirect codes:

HTTP Code	Status	Description
301	permanent	The resource has permanently moved
302	temp	The resource has temporarily moved
303	seeother	The resource has been replaced and refer to new resource
305	UseProxy	Use proxy to access site
307	Temp	The resource has temporarily moved
410	Tegone	The resource has permanently removed
