Will add a new security constraint:
For all paths:
if( match(path) && match(method) && match( transport ) )
then require("roles")
This is equivalent with adding a Container with the path,
method and transport.
Create a new sub-request in a given context, set the context "hint"
This is a particular case of sub-request that can't get out of
a context ( and we know the context before - so no need to compute it
again)
Note that session and all stuff will still be computed.
This is the entry point in tomcat - the connectors ( or any other
component able to generate Request/Response implementations ) will
call this method to get it processed.
Set default settings ( interceptors, connectors, loader, manager )
It is called from init if no connector is set up - note that we
try to avoid any "magic" - you either set up everything ( using
server.xml or alternatives) or you don't set up and then defaults
will be used.
