Abstract

A server system has a process manager, listeners and worker processes in which the listeners connect to worker processes. At server start-up, each listener connects with the process manager via a pipe published by the process manager. The process manager then provides information to each listener associating applications to application pools, and applications for which the listener is to “listen”. When the listener receives a request for which it is to listen, the listener starts a queue for the application or associated application pool. The process manager launches an appropriate worker process to handle requests in the listener'"'"'s protocol. The worker process then makes a connection with the listener.

Claims

1. A method for forming a connection between a listener and a worker process in a server using a process manager in the server, the method comprising:

receiving an indication from the listener to start a queue that is to be used in handling a server request from a client, the server request conforming to a protocol of a plurality of protocols, the indication specifying a protocol to be used in handling the server request, wherein the server can handle server requests in the plurality of protocols; and

launching the worker process, wherein the worker process and the listener form the connection to support communication between the server and the client using the specified protocol.

2. The method of claim 1, wherein the indication comprises the listener'"'"'s identity.

3. The method of claim 1, further comprising publishing a pipe that is to be used in receiving information from the listener.

4. The method of claim 1, further comprising configuring the listener to start a new queue, wherein the new queue is to be started in response to a request, from a client, that requires a new queue.

5. The method of claim 1, further comprising providing configuration to the listener, wherein the configuration information includes information associating applications and application pools.

6. The method of claim 5, wherein the configuration information is obtained from a configuration store.

7. The method of claim 1, further comprising invoking protocol handler in the worker process, wherein the protocol handler is to support communication according to the server request'"'"'s protocol.

8. The method of claim 7, wherein invoking a protocol handler comprises invoking a protocol handler corresponding to an application pool.

9. The method of claim 7, wherein invoking a protocol handler comprises invoking a protocol handler corresponding to an application.

10. The method of claim 7, further comprising selectively disabling an application or application pool in a listener.

11. A computer-readable medium having instructions for performing the method of claim 1.

12. An apparatus for forming a connection between a listener and a worker process in a server, the apparatus comprising:

means for receiving an indication from the listener to start a queue that is to be used in handling a server request from a client, the server request conforming to a protocol of a plurality of protocols, the indication specifying a protocol to be used in handling the server request, wherein the server can handle server requests in the plurality of protocols; and

means for launching the worker process, wherein the worker process and the listener form the connection to support communication between the server and the client using the specified protocol.

13. The apparatus of claim 12, wherein the indication comprises the listener'"'"'s identity.

14. The apparatus of claim 12, wherein the means for receiving further comprises means for publishing a pipe through which the listener exchanges information with the apparatus.

15. The apparatus of claim 12, further comprising means for configuring the listener to start a new queue, wherein the new queue is to be started in response to a request, from a client, that requires a new queue.

16. The apparatus of claim 12, further comprising means for providing configuration information to the listener, wherein the configuration information includes information associating applications and application pools

17. The apparatus of claim 16, wherein the means for providing configuration information obtains the configuration information from a configuration store.

18. The apparatus of claim 12, further comprising means for invoking protocol handler in the worker process, wherein the protocol handler is to support communication according to the server request'"'"'s protocol.

19. The apparatus of claim 18, wherein the means for invoking a protocol handler is to invoke a protocol handler corresponding to an application pool.

20. The apparatus of claim 18, wherein the means for invoking a protocol handler is to invoke a protocol handler corresponding to an application.

21. A machine readable medium having components to implement the apparatus recited in claim 12.

26. A machine readable medium having components to implement the component recited in claim 15.

22. A component to be used in a server of a client-server system, the component comprising:

a worker process host to support communication between the component and a process manager of the server;

a process manager host to manage applications included in the component to handle a request from a client of the client-server system; and

a first protocol handler to support a communication between the server and the client using a protocol of a plurality of supported protocols.

23. The component of claim 22, further comprising a plurality of protocol handlers that includes the first protocol handler.

24. The component of claim 22, further comprising a plurality of application domains associated with a plurality of applications used to handle requests.

25. The component of claim 22, further comprising an application manager to manage the plurality of application domains.

27. A system, comprising:

a plurality of clients;

a network coupled to the plurality of clients; and

a server, coupled to the network, the server including a process manager, and a plurality of listeners, wherein the process manager is configured to;

form a connection to a listener;

receive an indication from the listener to start a queue that is to be used in handling a server request conforming to a protocol of a plurality of supported protocols, the indication specifying a protocol of a plurality of supported protocols to be used in handling the server request; and

launching a worker process to handle the server request and to support communication between the server and the client using the specified protocol.

28. The system of claim 27, wherein the indication comprises the listener'"'"'s identity.

29. The system of claim 27, wherein the process manager is further to publish a pipe that is to be used in forming the connection between the process manager and the listener.

30. The system of claim 27, wherein the process manager is further to configure the listener to start a new queue, wherein the new queue is to be started in response to a request, from a client, that requires processing.

31. The system of claim 27, wherein the process manager is further to provide configuration information to the listener, wherein the configuration information includes information associating applications and application pools.

32. The system of claim 31, wherein the configuration information is obtained from a configuration store.

33. The system of claim 27, further comprising invoking protocol handler in the worker process, wherein the protocol handler is to support communication according to the server request'"'"'s protocol.

34. The system of claim 33, wherein invoking a protocol handler comprises invoking a protocol handler corresponding to an application.

35. The system of claim 33, wherein invoking a protocol handler comprises invoking a protocol handler corresponding to an application domain.
