Confluence behind Apache: How to address Confluence by subdomain and not by Tomcat context path?
Asked by Markus Kropf:

I have a server machine with a Confluence and an Apache server installed on it.  
The Apache server is publicly adressable by *[mycompany.com](http://mycompany.com)* :80.  
The Confluence application is in Tomcat context */confluence* .  
In the apache server I have a *\<VirtualHost\>* with *ServerName [confluence.mycompany.com](http://confluence.mycompany.com)* forwarding requests to*JkMount /\* worker1.*

My current setup results in URLs like *<http://confluence.mycompany.com/confluence/display/>...*

I would like to have URLs in the public like *<http://confluence.mycompany.com/display/>...*   

The point is, to adress the Confluence system by subdomain name, which I would like to show in the public, instead of by context path segment, which I prefer to use internally only.  

What is the recommended setup to get rid of the path prefix */confluence* ? Do I need a *\<Context path="/" docBase="../confluence"* in Tomcat? Is it possible/problematic to have Confluence at the root path in Tomcat? Or can I do the mapping without the*/confluence* path in Apache?

I'm not a major expert, but I have a similar setup (confluence behind apache proxy), maybe my setup will help answer your question. NOTE: I use mod_proxy, not mod_jk. FYI. My site is not publically accessible.

Apache setup:

```
&lt;VirtualHost *:80&gt;  ServerName     confluence.mydomain.com  ServerAlias    confluence  ErrorLog       /var/log/apache2/confluence-error.log  CustomLog      /var/log/apache2/confluence-access.log combined  ProxyRequests     Off  ProxyPreserveHost On  &lt;Proxy *&gt;    Order deny,allow    Allow from all  &lt;/Proxy&gt;  # Make sure the requests are redirected  ProxyPass        /  http://localhost:8280/  ProxyPassReverse /  http://localhost:8280/  &lt;Location /&gt;    Order allow,deny    Allow from all  &lt;/Location&gt;&lt;/VirtualHost&gt;
```

Tomcat Server.xml

(changes to connector, to add proxyName and proxyPort).

```
......        &lt;Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="8280" minProcessors="5"                   maxProcessors="75"                   enableLookups="false" redirectPort="8443" acceptCount="10" debug="0" connectionTimeout="20000"                   useURIValidationHack="false" URIEncoding="UTF-8"                   proxyName="confluence.mydomain.com" proxyPort="80"/&gt;...                &lt;Context path="" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true"&gt;......
```

Remeber to change "server base url" in confluence admin / general config to: <http://confluence.mydomain.com>

Hope this is of some use.

Gavin.

body: I would recommend using the same contextpath on your usual domain and on your subdomain.

You can use different on apache, but not on tomcat, so you can use some rewrite tools to handle this, but, I think, it will not be nice and easy. And Confluence can not handle different contextpaths. And it can not handle different baseurls. This might be an interesting problem to solve in your setup.

But to come back to your original question, keep one contextpath for all, and if you don't need /confluence I would recommend using / .If that is possible on your setup...
