Domain doesn't work without `www`

问题

When I type in my domain name like without the www (like http://example.com), it doesn't work and gives error message. However, when I add the www to it (like http://www.example.com), it works.

Isn't it supposed to work both ways (with and without the www)?

All you need is to add the following code to your root .htaccess file:

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

With the current version of apache, you need to do the following, which has changed compared to the previous versions:

cd /etc/apache2/sites-enabled

Now find the config file for your domain and edit it (the first three lines after <VirtualHost *:80> is what we need here):

<VirtualHost *:80>
        ServerName www.yourdomain.com
        ServerAlias yourdomain.com *.yourdomain.com
        ServerAdmin webmaster@localhost

        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>

</VirtualHost>

And now after saving changes to the file, you should reload Apache we server configuration with:

service apache2 reload

and it'll work!

P.S. You may also want not to add *.yourdomain.com to the end of your ServerAlias line.

to solve this issue

-> suppose you want mysubdomain.domain1.com

-> goto your dns records settings in your web panel ( cpanel , vestapanel etc ) of domain1.com

-> add there new A record with ip of your domain1.com and fill record/hostname field with @ // @ mean no www if you want www too then add another new A record and replace @ with www

-> save it

-> wait for dns changes to take place maybe take few hours

Alternatively, you could follow below steps which solves this problem, for sure, if you're using GoDaddy and google apps :

Go to Google Apps and sign in to domain management.
Then click on domain settings.
Then click on domain Names.
Then Click on words highlighted to set a redirect via google apps and you should see it done within 3 hours or MAX 2 DAYS (though it usually does not take more than a day in the rarest case).Just follow the simple english instructions there and you should see it done.

You need to change any full urls to paths. If your php include or other processes are linked using urls, it will only work one way.

$.ajax(
{       
    url:'/LAYOUT/process.php'
}

as oppose to the full url

$.ajax(
{       
    url:'https://www.yourdomain.com/LAYOUT/process.php'
}

Using a simple path will allow it to work both ways with or without www.
