htaccess subdomain redirect to port while keeping original url

问题

I have trouble getting this to work properly, what I'm trying to do is make http://subdomain.domain.com redirect to domain.com:8080 while keeping the original url "subdomain.domain.com"

Code so far:

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

Which does the redirect, but browser url changes to "http://domain.com:8080" which is not what I seek.

Thank you in advance!

For this to happen you need to enable mod_proxy in subdomain\.domain\.com. Once it is enabled try this rule in DocumentRoot/.htaccess of subdomain.domain.com:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^subdomain\.(domain\.com)$
RewriteRule ^ http://%1:8080%{REQUEST_URI} [L,NE,P]
