Abstract

A server system in typical operation has a process manager, multiple listeners (each to receive requests for its protocols) and multiple worker processes that are each able to handle requests in multiple protocols. At server start-up, each listener connects with the process manager via a pipe published by the process manager. The listener then receives information via the process manager that includes information defining the application(s) for which that listener is to “listen” and associating application(s) to application pool(s). When the listener receives a request for such an application, the listener starts a queue for the associated application pool. The listener may use a hierarchical matching scheme to determine the associated application or application pool from the requested application. 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 to form a connection between listeners and worker process in a server, the server including a process manager, a first listener to support requests in a first protocol and a second listener to support requests in a second protocol, the method comprising:

receiving information associating applications to application pools;

receiving a request for an application, the request conforming to the first protocol;

determining whether the requested application is one of the applications; and

obtaining an application pool identifier of an application pool associated with the requested application.

2. The method of claim 1, further comprising providing the application pool identifier to the process manager in starting a worker process to handle the request.

3. The method of claim 1, wherein determining whether the requested application is one of the applications comprises comparing a path portion of the request to identifiers of the applications.

4. The method of claim 3, wherein comparing a path portion of the request to identifiers of the applications further comprises determining a longest hierarchical match between the path portion of the request and the identifiers of the applications.

5. The method of claim 1, further comprising determining whether the requested application is disabled.

6. The method of claim 5, wherein determining whether the requested application is disabled comprises determining whether a binding portion of the request corresponds to an application that is specified as disabled in the information.

7. The method of claim 6, wherein the binding portion includes a protocol identifier.

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

28. The method of claim 1, further comprising determining whether the application associated with the requested application is disabled.

9. An apparatus to form a connection between listeners and worker process in a server, the server including a process manager, a first listener to support requests in a first protocol and a second listener to support requests in a second protocol, the apparatus comprising:

means for receiving information associating applications to application pools;

means for receiving a request for an application, the request conforming to the first protocol;

means for determining whether the requested application is one of the applications; and

means for obtaining an application pool identifier of an application pool associated with the requested application.

10. The apparatus of claim 9, further comprising means for providing the application pool identifier to the process manager in starting a worker process to handle the request.

11. The apparatus of claim 9, wherein the means for determining whether the requested application is one of the applications comprises means for comparing a path portion of the request to identifiers of the applications.

12. The apparatus of claim 11, wherein the means for comparing a path portion of the request to identifiers of the applications further comprises means for determining a longest hierarchical match between the path portion of the request and the identifiers of the applications.

13. The apparatus of claim 9, further comprising means for determining whether the requested application is disabled.

14. The apparatus of claim 13, wherein the means for determining whether the requested application is disabled further comprises means for determining whether a binding portion of the request corresponds to an application that is specified as disabled in the information.

15. The apparatus of claim 14, wherein the binding portion includes a protocol identifier.

16. A machine readable medium having components to implement the apparatus recited in claim 9.

17. A computer readable medium having a data structure to be used in forming a connection between listeners and worker process in a server, the server including a process manager, a first listener to support requests in a first protocol and a second listener to support requests in a second protocol, the computer readable medium comprising:

a first plurality of fields to define bindings having a protocol and a binding information; and

a second plurality of fields to associate applications and application pools,

wherein the first and second listeners are configured to receive requests that each include a binding portion referencing binding information and a path portion referencing an application.

18. The computer readable medium of claim 17, the data structure includes a field to indicate whether a protocol for an application pool is enabled.

19. The computer readable medium of claim 17, wherein the data structure is in an XML format.

20. A system, comprising:

a plurality of clients;

a network coupled to the plurality of clients; and

a server, coupled to the network, including a process manager, a configuration store, and a plurality of listeners to receive requests in a plurality of procotols, wherein each listener is configured to;

receive information associating applications to application pools;

receive a request for an application, the request conforming to one of the plurality of protocols;

determine whether the requested application is one of the applications; and

obtain an application pool identifier of an application pool associated with the requested application.

21. The system of claim 20, wherein each listener is further configured to provide the application pool identifier to the process manager in starting a worker process to handle the request.

22. The system of claim 20, wherein each listener is further configured to compare a path portion of the request to identifiers of the applications.

23. The system of claim 22, wherein each listener is further configured to determine a longest hierarchical match between the path portion of the request and the identifiers of the applications.

24. The system of claim 20, wherein each listener is further configured to determine whether the requested application is disabled.

25. The system of claim 24, wherein each listener is further configured to determine whether a binding portion of the request corresponds to an application that is specified as disabled in the information.

26. The system of claim 25, wherein the binding portion includes a protocol identifier.

27. The system of claim 20, wherein each listener is further configured to determine whether the application associated with the requested application is disabled.
