All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class WmsDispatcher

extends Dispatcher

Routes requests made at the top-level URI to appropriate interface servlet. Note that the logic of this method could be generously described as 'loose.' It is not checking for request validity in any way (this is done by the reqeust- specific servlets). Rather, it is attempting to make a reasonable guess as to what servlet to call, given that the client is routing to the top level URI as opposed to the request-specific URI, as specified in the GetCapabilities response. Thus, this is a convenience method, which allows for some slight client laziness and helps explain to lost souls/spiders what lives at the URL. Due to the string parsing, it is much faster (and recommended) to use the URIs specified in the GetCapabablities response. Currently does not support post requests, but most requests for this will likely come with get.
