Redirect all pages of one TLD to another

问题

\I'm darn nearly pulling my hair out trying to figure this out tonight. I'm hoping someone can help me out.

I have 3 TLD's for a site, similar to the following:

• www.domain.com
• www.domain.org
• www.domain.net

They are all located in the same directory.

I would like to set up 301 redirects so that all pages of the .org and .net point to their respective pages at the .com location.

For example, domain.net/topic/page as well as www.domain.net/topic/page should permanently redirect to www.domain.com/topic/page.

Currently, I am using the code below which only redirects the .net and .org home pages to the .com home page.

RewriteCond %{HTTP_HOST} !^(www\.)?domain\.com$ [NC]
RewriteRule .?$ http://www.domain.com%{REQUEST_URI} [R=301,L]

Thank you for your time,

Casey

回答1:

This one is based on your example with minor modification:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^(www\.)?domain\.com$ [NC]
RewriteRule ^(.*) http://www.domain.com/$1 [R=301,NE,L]

NC, R=301 and L are pretty obvious. The NE is for no-escape and it prevents query string variables from being escaped twice. The ^(.*) does not need a / in most cases.

Note: 301 permanent redirect responses will be cached by the browser so clear your browser cache every now and then while testing. Otherwise you may not see the result of changes you make.

RewriteCond %{HTTP_HOST}   domain\.(org|net) [NC]
RewriteRule ^/(.*)         http://www.domain.com/$1 [L,R=301]

There are many other way to write the Cond, this is how I did mine - a positive compare. Yours is a negative compare, but it has the drawback that if someone doesn't send a host header it will redirect forever, on the plus you don't need to list all the domains to redirect. Also you can add a rule to redirect .com without www if you want.

For the Rule the trick is the () in the expression - this captures that part of the url for use later with the $1

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com$1 [R=301,L]

This redirects every request to www.domain.com including querystring and request-uri if the host is not www.domain.com
