.htaccess Rewriting Tomcat Server

Question

I am writing a website using Railo. My code is to be deployed on a Railo Server running on Tomcat, overlayed on a regular Apache+PHP server.

I need to send all requests to http://subdomain.myserver.co.uk/ and its child files to the directory /public_html/railo/tomcat/webapps/ROOT/subdomain/ directory.

I defined a subdomain in cPanel, with the document root as /public_html/railo/tomcat/webapps/ROOT/subdomain/, but still requests to http://subdomain.myserver.co.uk/ display files in /public_html/railo/tomcat/webapps/ROOT/. I can view my files if I request http://subdomain.myserver.co.uk/subdomain/

I've been fiddling with the .htaccess files for quite some time now, but I'm stuck

Is there any way I can do what I'm trying to achieve, or am I resigned to get those pages using http://subdomain.myserver.co.uk/subdomain/

Solution

Put the following into /public_html/railo/tomcat/webapps/ROOT/.htaccess:

RewriteEngine on
RewriteCond %{HTTP_HOST} enterprise.myserver.co.uk
RewriteRule (.*) /public_html/railo/tomcat/webapps/ROOT/lfEnterprise$1

Here the target of the RewriteRule is a filesystem path, not a URL as is more common. RewriteRule will accept either, and figure out which one is meant. Please see the RewriteRule documentation for that and more.

Where do I put this htaccess? in the ROOT directory?

Edited to clarify that.

So let me demystify things a bit... My subdomain is enterprise.myserver.co.uk but my app resides in /public_html/railo/tomcat/webapps/ROOT/lfEnterprise Also this is a Tomcat server overlayed on an Apache, so please keep that in mind.

Edited again. I don't know Tomcat, but I don't think it matters here.

Edited again to remove one of the RewriteConds.
