How to Park a Domain on an Addon Domain
If you're using a shared host with CPanel, no doubt you are getting familiar with addon domains and parked domains. You may have parked a domain already on your main domain. Recently however, I wanted to park a domain on an addon domain, and was told that this is impossible. Well, I've found of using the .htaccess file that works well enough.
Just to be clear: an addon domain is a fully functional domain that can be created from your cpanel. Once it's created it will have it's own email, and it's own folder from within the public_html directory. Parked domains are place holder sites. You park them on top of another site and they become a single page of the site you park it on.
Basically I had this situation, domain names have been changed of course:
- www.mysite1.com is an addon domain in my shared hosting account. The folder is /public_html/mysite1/.
- www.mysite2.com I want to point to www.mysite1.com. The folder is /public_html/mysite2/.
I was told to just set up a simple redirect. I could have done this with PHP, and put index.php in /public_html/mysite2/, redirecting to www.mysite1.com. Or I could have put a simple redirect rule in .htaccess. But this would only work at the root domain level. In other words, if someone requested www.mysite2.com/support (or any other page/directory), it would always redirect to the root domain of www.mysite1.com. So I dug up this good workaround with .htaccess, which allows any request to be forwarded to the same page/directory of another domain. So www.mysite2.com/support would go to www.mysite1.com/support.
Here's the .htaccess code, put it in the folder you wish to redirect. In my case that's /public_html/mysite2/
RewriteCond %{HTTP_HOST} ^mysite2.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.mysite2.com$
RewriteRule ^(.*)$ http://www.mysite1.com/$1 [R=301,L]
By the way, the trailing slash is vital for this to work.
