On a machine running Tomcat and Apache, you can set things up so that instead of having to type Tomcat URLs with ":8080" on the end of the domain, you use a proxy to redirect that traffic to Tomcat.

I had to adjust two files: httpd.conf in my \conf directory, and server.xml in my \conf directory. My edited files are attached.

For the Apache configuration (httpd.conf), you have to do three things:

1. Uncomment three lines by deleting the "#" at the beginning of the line:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_http_module modules/mod_proxy_http.so

2. Add the following lines directly below all the "LoadModule" commands:

TraceEnable off
ProxyRequests Off
ProxyPreserveHost On
<ProxyMatch http://[^/]*/*>
Order deny,allow
Allow from 127.0.0.1
</ProxyMatch>

3. For each webapp that you want redirected, add the following lines (example below is for my geoserver webapp, and "malachite" is the domain name for my server):

ProxyPass /geoserver http://malachite:8080/geoserver
ProxyPassReverse /geoserver http://malachite:8080/geoserver
<Location /geoserver>
Order allow,deny
Allow from all
</Location>

For the Tomcat configuration (server.xml), find the "Service" element, and the "Connector" child element. To that "Connector" element, add the attributes proxyName="<your domain name (malachite in my case)>" and proxyPort="80".

NOTE: I had to change the extension on the httpd.conf file in order to upload it here. On your computer the file has to be named "httpd.conf" and not "httpd.txt"
