Abstract

Methods, systems, and computer program products for applying actions during server system processing. Functional processing blocks where actions may be applied to a service request are identified. actions are dynamically associated with functional processing blocks. During execution of a functional processing block, a check is performed to determine whether an action is associated with the functional processing block. If an action is associated with a functional processing block, the action is applied during the functional processing block'"'"'s execution. An evaluation may be performed to determine if an action should be applied before or after the functional processing block. The server system may comprise an XML data repository, providing access to XML data, based on identity information which is received with a client system request. A portion of the server system may be described in accordance with an XML schenia.

Claims

1. A server system for providing one or more services, the server system comprising one or more computer-readable media having computer-executable instructions for implementing a method for dynamically executing one or more filtering functions at any of one or more processing steps that may occur in providing the one or more services to one or more client systems, wherein the method comprises:

an act of defining one or more processing steps that are performed by a server system in providing one or more services in response to a request, the one or more processing steps being defined within a plurality of processing layers of the server, the plurality of processing layers including at least a parsing layer;

an act of dynamically assigning at least one filtering function to at least one of the one or more processing steps, wherein the filtering function is configured to terminate further processing based on content in the request;

at each processing step that is processed, an act of dynamically evaluating whether or not any filtering function has been assigned; and

at each processing step that is processed and has at least one assigned filtering function, an act of executing the at least one assigned filtering function by terminating further processing when the request contains particular content.

2. A server system as recited in claim 1, further comprising an act of evaluating whether the at least one dynamically assigned filtering function should be executed either before or after the at least one of the one or more processing steps.

3. A server system as recited in claim 1, wherein the one or more processing steps enable processing requests from client systems, and wherein the method further comprises:

an act of receiving the request for the one or more services from the client system;

based on the request for the one or more services, an act of generating a response; and

an act of sending the response to the client system.

4. A server system as recited in claim 3, wherein the request and the response comprise data organized hierarchically within a network message, and wherein the hierarchically organized data comprises extensible Markup Language (“

XML”

) formatted data, and wherein the network message comprises a Simple Object Access Protocol (“

SOAP”

) network message.

5. A server system as recited in claim 4, wherein the hierarchically organized data comprises binary data.

6. A server system as recited in claim 1, wherein the method further comprises an act of defining one or more filtering functions that may be executed at any of the one or more defined processing steps.

7. A server system as recited in claim 1, wherein the server system comprises an eXtensible Markup Language (“

XML”

) data repository providing access to XML data based on identity information that is received with the request from a client system for the one or more services provided by the server system.

8. A server system as recited in claim 1, wherein the method further comprises an act of describing at least a portion of the server system in accordance with an eXtensible Markup Language (“

XML”

) schema.

9. A server system as recited in claim 8, wherein the plurality of layers further comprise a security layer, a cryptography layer, and a service layer.

10. A server system as recited in claim 9, wherein the at least one filtering function comprises terminating further processing when the request contains at least one of spam, pornographic material, or unsolicited content.

11. A server system as recited in claim 1, wherein executing the assigned function detects a filtering condition in a request received from a client system, wherein the method further comprises:

an act of terminating any further processing on the request; and

an act of generating a response that includes information about the filtering condition.

12. A server system as recited in claim 1, wherein the method further comprises an act of dynamically unassigning the at least one filtering function from the at least one of the one or more processing steps.

13. A server system as recited in claim 1, wherein the parsing layer comprises means for determining that there are errors with the request.

14. A server system comprising one or more functional processing blocks and one or more computer-readable media having computer-executable instructions for implementing a method for dynamically applying one or more filtering actions while executing any of the one or more functional processing blocks, wherein the method comprises:

within a server system providing one or more services in response to a client request, a step for identifying one or more functional processing blocks where one or more filtering actions may be applied to one or more requests directed to the one or more services, wherein the functional processing blocks are identified within a plurality of processing layers of the server, the plurality of processing layers including at least a parsing layer;

for at least one of the one or more functional processing blocks, a step for dynamically associating at least one filtering action, the filtering action configured to terminate further processing based on content in the request;

a step for checking whether or not any filtering action has been associated with a particular functional processing block during execution of the particular functional processing block; and

during execution of any functional processing block with one or more associated actions, a step for applying the one or more associated filtering actions by terminating further processing when the request contains particular content.

15. A server system as recited in claim 14, wherein the step for dynamically associating at least one filtering action comprises an act of evaluating whether the at least one dynamically associated filtering action should be applied before or after the at least one of the one or more functional processing blocks.

16. A server system as recited in claim 14, wherein the method further comprises a step for responding to a client system based on the request for the one or more services from the client system.

17. A server system as recited in claim 14, wherein the request and a response to the client system comprise data organized hierarchically within a network message, the hierarchically organized data comprising extensible Markup Language (“

XML”

) formatted data, and the network message comprising a Simple Object Access Protocol (“

SOAP”

) network message.

18. A server system as recited in claim 14, wherein the server system comprises data that can be manipulated with extensible Markup Language (“

XML”

), and wherein access to the data is governed by the identity of the requestor.

19. A server system as recited in claim 14, wherein the server system comprises a plurality of processing layers, and wherein the plurality of layers comprise at least one of a security layer, a cryptography layer, and a service layer, and wherein the at least one filtering action comprises terminating further processing when the request contains at least one of spam, pornographic material, or unsolicited content.

20. A server system as recited in claim 14, wherein the method further comprises a step for dynamically disassociating the at least one filtering action from the at least one of the one or more functional processing blocks.
