Abstract

The invention relates to systems and method for rerouting web service messages. A method for performing web services includes receiving a web service request from a client, rerouting the web service request to a server, receiving results of the web service request, and sending the results of the web service request to the client. The rerouting can be used with messages/requests formulated in Simple Object Access Protocol (also referred to as Service Oriented Architecture Protocol, or simply SOAP).

Claims

receiving a web service request arranged in SOAP protocol from a client at a web services hosting server;

rerouting the received web service request arranged in SOAP protocol to a server by acting as the client and rerouting the request to an existing connection to the server based on an identity of the server;

receiving results of the web service request from the server;

sending the results of the web service request to the client; and

determining, prior to rerouting the received web service request arranged in SOAP protocol, the identity of the server to which the web service request is sent, from among a plurality of servers, each respectively connected to an associated database, by extracting, based on programming code resident in the web services hosting server, the identity of which one of the plurality of servers is best suited to handle the web service request in SOAP protocol from data contained within the web service request, wherein the determining is performed by the web services hosting server,

wherein the server reuses an existing database connection to the database respectively associated with the server, such that the database connection has already been initialized and a database connection pool has already been established before the web server request is rerouted to the server,

wherein the web service hosting server sends the results of the web service request received from the server to the client in SOAP protocol without having to convert the results of the web service request from the server into a new format, and

wherein the web services hosting server reuses a same Web Services Description Language (WSDL) file to generate a same set of web services code to deploy to each of the plurality of servers.

2.

6. The method of claim 1, wherein the steps of claim 1 are provided by a service provider under at least one of:

a subscription, fee agreement, and based on advertising content to one or more third parties.

7. The method of claim 1, wherein a service provider at least one of creates, maintains, deploys and supports a computer infrastructure that performs at least one of the steps of claim 1.

15. The method of claim 3, wherein the web services hosting server is configured to reroute the web service request arranged in SOAP protocol to an appropriate one of the plurality of web applications servers.

16. The method of claim 15, wherein each one of a plurality of web applications servers is associated with a respective geographic region.

17. The method of claim 16, wherein the web services hosting server communicates with the client using a wired communications link.

18. The method of claim 1, wherein the web service request arranged in SOAP protocol rerouted to the server is the same request as the received web service request arranged in SOAP protocol.

19. The method of claim 18, wherein the web services hosting server is a common server requesting the web service request as the client.

20. The method of claim 1, wherein:

the web services hosting server acts as the client by acting as the originator for the web service request arranged in SOAP protocol and bypasses redirect technology.

8. A method for handling web services, comprising:

providing a computer infrastructure structured and arranged to;

receiving a web service request arranged in a SOAP protocol from a client at a web services hosting server;

rerouting the web service request arranged in SOAP protocol to a server by acting as the client and rerouting the request to an existing connection to the server based on an identity of the server;

receiving results of the web service request from the server; and

sending the results of the web service request to the client,

wherein the web services hosting server comprises programming code that operates to cause the web service hosting server to determine, based on programming code resident in the web services hosting server, prior to rerouting the received web service request arranged in SOAP protocol, the identity of the server, from among a plurality of servers, best suited to handle the web service request by analyzing data contained within the web service request,

wherein each of the plurality of servers is respectively connected to an associated database, and wherein the server reuses an existing database connection to the database respectively associated with the server, such that the database connection has already been initialized and a database connection pool has already been established before the web server request is rerouted to the server,

wherein the web service hosting server sends the results of the web service request received from the server to the client in SOAP protocol without having to convert the results of the web service request from the server into a new format, and

wherein the web services hosting server reuses a same Web Services Description Language (WSDL) file to generate a same set of web services code to deploy to each of the plurality of servers.

9. The method of claim 8, wherein the computer infrastructure comprises a web services hosting server.

10. The method of claim 9, wherein,

the web services hosting server functions as a host when receiving the web service request from the web services client, and when sending the result of the web service request to the web services client, and

the web services hosting server functions as the client when sending the web service request to the one of the plurality of web applications servers, and when receiving the result of the web service request from the one of the plurality of web applications servers.

11. The method of claim 9, wherein:

the web services client is one of a plurality of web services clients, and

the web services hosting server is arranged to reroute web services requests from any of the plurality of web service clients.
