java.lang.Objectorg.apache.http.protocol.HttpService
public class HttpService
HttpService is a server side HTTP protocol handler based in the blocking
I/O model that implements the essential requirements of the HTTP protocol
for the server side message processing as described by RFC 2616.
HttpService relies on HttpProcessor
to generate mandatory protocol
headers for all outgoing messages and apply common, cross-cutting message
transformations to all incoming and outgoing messages, whereas individual
HttpRequestHandler
s are expected to take care of application specific
content generation and processing.
HttpService relies on HttpRequestHandler
to resolve matching request
handler for a particular request URI of an incoming HTTP request.
HttpService can use optional HttpExpectationVerifier
to ensure that
incoming requests meet server's expectations.

Create a new HTTP service. |
Method Summary | |
---|---|
protected void |
doService(HttpRequest request,
HttpResponse response,
HttpContext context)
The default implementation of this method attempts to resolve an HttpRequestHandler for the request URI of the given request
and, if found, executes its
HttpRequestHandler.handle(HttpRequest, HttpResponse, HttpContext)
method. |
HttpParams |
getParams()
|
protected void |
handleException(HttpException ex,
HttpResponse response)
Handles the given exception and generates an HTTP response to be sent back to the client to inform about the exceptional condition encountered in the course of the request processing. |
void |
handleRequest(HttpServerConnection conn,
HttpContext context)
Handles receives one HTTP request over the given connection within the given execution context and sends a response back to the client. |

Super-classes can override this method in order to provide a custom implementation of the request processing logic.
