public boolean init(Server server,
String prefix)
Handler
init in interface Handlerserver - The HTTP server that created this Handler.
Typical Handlers will use Server.props
to obtain run-time configuration information.prefix - The handlers name.
The string this Handler may prepend to all
of the keys that it uses to extract configuration information
from Server.props. This is set (by the Server
and ChainHandler) to help avoid configuration parameter
namespace collisions.
true if this Handler initialized
successfully, false otherwise. If
false is returned, this Handler
should not be used.
public boolean respond(Request request)
throws IOException
respond in interface Handlerrequest - The Request object that represents the HTTP
request.
true if the request was handled. A request was
handled if a response was supplied to the client, typically
by calling Request.sendResponse() or
Request.sendError.
IOException - if there was an I/O error while sending the response to
the client. Typically, in that case, the Server
will (try to) send an error message to the client and then
close the client's connection.
The IOException should not be used to silently
ignore problems such as being unable to access some
server-side resource (for example getting a
FileNotFoundException due to not being able
to open a file). In that case, the Handler's
duty is to turn that IOException into a
HTTP response indicating, in this case, that a file could
not be found.
