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 ^(.*)$ [L] 

...but it does not work.

Is there a way to make it work?

You could always use a simple VirtualHost:

<VirtualHost *:80> ServerName b.website.com RedirectPermanent / </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 ^(.*)$ [L] 

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 # In a .httaccess file ... RewriteRule ^(.*)$ [R=302,L] 

Specify directory matching patterns

You could only redirect requests that match some pattern.

# In a VirtualHost file ... RedirectMatch [301|302] ^/public/(.*)$ # In a .httaccess file ... RewriteRule ^/public/(.*)$ [R=302,L]
