Redirecting both http and https requests to new ho

问题:

In Apache 2.4.6, I would like to redirect requests from http://A.org/foo and https://A.org/foo to https://B.org/foo.

I am using the following directives:

<VirtualHost 1.2.3.4:80>
     ServerName B.org
     ServerAlias A.org
     RewriteEngine on
     RewriteCond %{HTTP_HOST} !^B.org$
     RewriteRule ^/(.*)$ https://B.org/$1 [R=permanent,L]
</VirtualHost>

<VirtualHost 1.2.3.4:443>
     ServerName B.org
     ServerAlias A.org
     RewriteEngine on
     RewriteCond %{SERVER_PORT} ^443(s)
     RewriteCond %{HTTP_HOST} !^B.org$
     RewriteRule ^/(.*)$ https://B.org/$1 [R=permanent,L]
</VirtualHost>

When I visit http://A.org/foo, this redirects to https://B.org/foo (correct).

When I visit https://A.org/foo, this loads https://B.org/foo but does not rewrite the URL. So I get an SSL certificate domain mismatch error from the web browser.

Is there something wrong with the second VirtualHost directive which would keep the URL from being rewritten?

回答1:

The SSL certificate has to be validated before the redirect can be issued, so you will need to use a certificate that is valid for 'A.org' within the VirtualHost that is issuing the redirect from https://A.org/, and separate it from the VirtualHost serving https://B.org/.

The line checking server port is not necessary because the VirtualHost only serves that port anyway. Just remove it.

Here's an outline with the rules also slightly tweaked for aesthetics which you may or may not prefer!

<VirtualHost 1.2.3.4:80>
     ServerName B.org
     ServerAlias A.org
     RewriteEngine on
     RewriteCond %{HTTP_HOST} !=B.org
     RewriteRule ^(.*)$ https://B.org$1 [R=permanent,L]
</VirtualHost>

<VirtualHost 1.2.3.4:443>
     ServerName A.org
     RewriteEngine on
     RewriteRule ^(.*)$ https://B.org$1 [R=permanent,L]
</VirtualHost>

<VirtualHost 1.2.3.4:443>
     ServerName B.org
</VirtualHost>
