Abstract

A method, apparatus, and article of manufacture for providing connectionless processing of client requests in a client-server computer system is disclosed. After forming a client-server connection, a client sends a request to a server. A key is associated with the request for identifying the request. The client-server connection is then terminated. The server processes the client request and produces a result, which the server stores for later reporting to the client. At a later point in time, a second client-server connection is formed. The client transmits the previously assigned key to the server. The server retrieves from storage the result from the earlier-processed request and transmits the result to the client.

Claims

1. A method of providing connectionless processing of client requests of a server, including the steps of:

(a) forming a client-server connection;

(b) transmitting a request from a client to a server;

(c) associating a key with the request for identifying the request;

(d) terminating the client-server connection;

(e) processing the request and producing a result at the server; and

(f) storing the result at the server for later reporting to the client when the client identifies the request by the associated key.

2. The method of claim 1, further including the steps of:

forming a second client-server connection;

transmitting the key from the client to the server; and

transmitting the result to the client.

3. The method of claim 1, wherein the step of associating a key with the request includes the server generating the key and transmitting the key to the client.

4. The method of claim 1, wherein the method of providing connectionless processing of client requests of a server is an optional alternative to processing of client requests while maintaining a client-server connection, wherein the connectionless processing option is specified in the step of transmitting a request from a client to a server.

5. The method of claim 2, wherein the method of providing connectionless processing of client requests of a server is an optional alternative to processing of client requests while maintaining a client-server connection, wherein the connectionless processing option is specified in the step of transmitting a request from a client to a server.

6. The method of claim 5, wherein the step of associating a key with the request includes the server generating the key and transmitting the key to the client.

7. A computer readable program storage medium tangibly embodying a program of instructions, executable by a computer to achieve connectionless processing of client requests of a server, to perform the steps of:

(a) forming a client-server connection;

(b) receiving a request from a client;

(c) associating a key with the request for identifying the request;

(d) terminating the client-server connection;

(e) processing the request and producing a result at the server; and

(f) storing the result at the server for later reporting to the client when the client identifies the request by the associated key.

8. The computer readable program storage medium of claim 7, wherein said program of instructions includes further instructions to perform the steps of:

forming a second client-server connection;

receiving the key from the client; and

transmitting the result to the client.
