Just like pages also resources can be mounted to a specific path. Class @WebApplication@ provides method @mountResource@ which is almost identical to @mountPage@ seen in [paragraph 10.6.1|guide:urls_6]:

{code}
@Override
public void init() {
  super.init();
  //resource mounted to path /foo/bar
  ResourceReference resourceReference = new ResourceReference("rssProducer"){
     RSSReaderResource rssResource = new RSSReaderResource();
     @Override
     public IResource getResource() {
	return rssResource;
  }};
  mountResource("/foo/bar", resourceReference);
}
{code}

With the configuration above (taken from project @CustomResourceMounting@) every request to /foo/bar will be served by the custom resource built in the previous paragraph. 

Parameter placeholders are supported as well:

{code}
@Override
public void init() {
  super.init();
  //resource mounted to path /foo with a required indexed parameter
  ResourceReference resourceReference = new ResourceReference("rssProducer"){
     RSSReaderResource rssResource = new RSSReaderResource();
     @Override
     public IResource getResource() {
	return rssResource;
  }};
  mountResource("/bar/${baz}", resourceReference);
}
{code}
