I want to know:

How to redirect from ..


to be


via .htaccess or CPanel?

As the SSL only installed on the one without "www", and when I visit the "www" one, I get SSL error.

The whole .htaccess file:

# The line just below this section: 'Options +FollowSymLinks' may cause problems
# with some server configurations.  It is required for use of mod_rewrite, but may already
# be set by your server administrator in a way that dissallows changing it in
# your .htaccess file.  If using it causes your server to error out, comment it out (add # to
# beginning of line), reload your site in your browser and test your sef url's.  If they work,
# it has been set by your server administrator and you do not need it set here.

## Can be commented out if causes errors, see notes above.
Options +FollowSymLinks

## Mod_rewrite in use.

    • This is probably not the site you are looking for! You attempted to reach www.iravin.com, but instead you actually reached a server identifying itself as eravin.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of www.iravin.com. You should not proceed, especially if you have never seen this warning before for this site.

You have both domains (example.com and www.example.com) on the same IP address. Then you have opened port 80 for HTTP and port 443 for HTTPS. As you have noticed, the port is open for all domains on the server; it can't be closed for just one domain while remaining open for any other.

When a client connects to https://www.example.com, it will start with the SSL negotiation, and the user will get a warning that the SSL certificate does not match. Any redirect that you create will happen only after the SSL negotiation, so they will still be getting the SSL certificate warning.

You should get a certificate that is either a wildcard domain certificate (i.e. one that matches *.example.com) or one that has www.example.com as a Subject Alternate Name to only domain-name.com. That way both www.example.com and example.com will work without warnings.

There is more information about SSL certificates and webservers here: Q: Multiple SSL domains on the same IP address and same port?

To redirect with 301 from www.example.com to no-www URL use this:

RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%2://%1%{REQUEST_URI} [L,R=301]

or this one:

RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
