All URLs generated by the framework consist of the the path to the servlet, and up to three query parameters.
service
: the name of the service that will be used
to processes the request.
context
: contextual information needed by the service; typically
the name of the page or component involved. Often there are several pieces of
information, separated by slashes.
sp
: additional parameters that can be made available to
the component. This is used by a DirectLink
component. If there is more than one
service parameter, then there will be multiple sp
parameters in the URL.
