An absolute URL begins with a protocol, usually http e.g. http://www.ebasetech.com. Note that the protocol is required for an absolute URL;
if the protocol is missing, the URL will be treated as a relative URL.
A relative URL does not begin with a protocol and is resolved as being relative to the web application root. In the supplied Tomcat system, this is ..userdata/apps/ebase/webapp
e.g. a relative URL of images/helpimage1.gif will resolve to ..userdata/apps/ebase/webapp/images/helpimage1.gif.
A URL can be either absolute or relative.
