Apache2 - Redirecting a subdomain to another URL

I have two subdomains, a.website.com and b.website.com, pointing to the same IP address. I want to redirect b.website.com to a.website.com:8080. I have this in my .htaccess file...

RewriteEngine on
RewriteCond {HTTP_HOST} b\.website\.com
RewriteRule ^(.*)$ http://b.website.com:8080$1 [L]

...but it does not work.

Is there a way to make it work?

Try adding the following to .htaccess in the parent directory above the directory of interest: RedirectMatch ^/foo/$ /foo/bar/ or RedirectMatch ^/foo/$ /bar/baz/. Also see How to get apache2 to redirect to a subdirectory.

You could always use a simple VirtualHost:

<VirtualHost *:80>
  ServerName b.website.com
  RedirectPermanent / http://a.website.com:8080/
</VirtualHost>

If you prefer to go with the .htaccess file, you're just missing a % sign on the Rewrite Condition:

RewriteEngine on
RewriteCond %{HTTP_HOST} b.website.com
RewriteRule ^(.*)$ http://a.website.com:8080$1 [L]

3This works fine. I had a loop redirect problem, because I was pointing a subdomain to a subfolder, and that subfolder was redirecting. Now, I redirect the subdomain to the URL that corresponds to the folder, and the 2nd redirection happens just fine! – Paschalis – 2014-07-12T09:29:03.510

How to do ot to preserve http:// or https://, whatever way b.website.com was accessed in the first place? – Golar Ramblar – 2018-06-02T08:27:08.793

I tried both and they didn't work. I have mod_rewrite enabled and I have the VirtualHost in a separate site file. Is there anything that I'm missing? – Technius – 2013-05-21T05:16:56.273

Complementing the main answer

Redirect type

You can explicitly specify the type of redirect you pretend.
I suggest you use a temporary redirect (302) while testing the redirection rule.

# In a VirtualHost file
...
Redirect [301|302] /old_location http://new_domain/newlocation


# In a .httaccess file
...
RewriteRule ^(.*)$ http://new_domain/$1 [R=302,L]

Specify directory matching patterns

You could only redirect requests that match some pattern.

# In a VirtualHost file
...
RedirectMatch [301|302] ^/public/(.*)$ http://public.example.com/$1


# In a .httaccess file
...
RewriteRule ^/public/(.*)$ http://public.example.com/$1 [R=302,L]
