Apache2 RedirectMatch 在特定情况下不起作用

Question

I have a server using apache2 that redirects all HTTP requests to HTTPS:

<VirtualHost *:80>
        ServerName www.mydomain.com.au
        RedirectMatch permanent ^/?(.*) https://www.mydomain.com.au/$1
</VirtualHost>

<VirtualHost *:80>
        ServerName mydomain.com.au
        RedirectMatch permanent ^/?(.*) https://www.mydomain.com.au/$1
</VirtualHost>

It works perfectly with the www domain but whenever I try to access the 'bare' domain I get the error:

Not Found
The requested URL / was not found on this server.

The most baffling thing is that the HTTPS version works:

<VirtualHost *:443>
        ServerName mydomain.com.au
        RedirectMatch permanent ^/?(.*) https://www.mydomain.com.au/$1
        #...
</VirtualHost>

If I for example try to GET https://mydomain.com.au/contact , it will correctly redirect to https://www.mydomain.com.au/contact . However, it will fail if I do the same thing with HTTP. Why?

Answer 1

You shouldn't have 2 entries for VirtualHost *:80 You can use ServerAlias for www and have a single entry:

<VirtualHost *:80>
        ServerName mydomain.com.au
        ServerAlias www.mydomain.com.au
        RedirectMatch permanent ^/?(.*) https://www.mydomain.com.au/$1
</VirtualHost>

ServerAlias declares alternative names that can be used to address the same site as in ServerName .

Answer 2

It turns out that the problem was that my VirtualHost settings were being overwritten in sites-available/000-default.conf. I changed the therein to have the configuration suggested by anubhava and it's working fine.
