Managing and securing manageable resources in stateless web server architecture using servlet filters
Access is controlled to managed resources in a stateless web server architecture including a stateless web server computing platform; a resource locator map portion of the stateless web server computing platform providing a unique resource locator code representing each managed resource in a stateless web server architecture, wherein the managed resource is assigned to a plurality of application program components; a set of servlet filters disposed in a portion of the stateless web server computing platform, each servlet filter associated with one of the application program components; a resource locator matcher portion of the stateless web server computing platform, responsive to a user request to a unique resource locator, matching a pattern in the user request to one or more of the application program components using a corresponding servlet filter; and a request dispatcher portion of the stateless web server computing platform sending the user request to the matched application program component, wherein the application program component receives and processes the user request.
1. A computer-based method comprising:
in a stateless web server:
extracting, by a computer, a request pattern from a valid relative path portion of a validly-formatted Uniform Resource Locator request;
mapping, by a computer, at least a portion of the extracted request pattern to one or more application program components;
responsive to the mapping, performing, by a computer, security access to the one or more application program components according to one or more associated security constraints, wherein at least one security constraint comprises at least a portion of the extracted request pattern, and wherein different security constraints are associated with different extracted request patterns; and
sending, by a computer to a requester, a Uniform Resource Locator request to the mapped application program component, thereby providing improved management to administration of computer resources in a stateless web server which are non conformant to rules of a central administration unit.
2. The computer-based method as set forth in claim 1 wherein the mapping is performed by one or more associated servlet filters.
3. The computer-based method as set forth in claim 1 wherein different attributes are represented by respective resource locators within the extracted request pattern.
4. The computer-based method as set forth in claim 1 wherein the security constraints are stored in a web deployment descriptor disposed in computer storage memory.
5. The computer-based method as set forth in claim 3 wherein security constraints for each attribute are stored in a web deployment descriptor disposed in computer storage memory.
6. A computer program product comprising:
a computer-readable, storage memory device; and
program instructions embodied by the computer-readable, storage memory device for causing a computer processor to perform steps comprising:
in a stateless web server:
extracting a request pattern from a valid relative path portion of a validly-formatted Uniform Resource Locator request;
mapping at least a portion of the extracted request pattern to one or more application program components;
responsive to the mapping, performing security access to the one or more application program components according to one or more associated security constraints, wherein at least one security constraint comprises at least a portion of the extracted request pattern, and wherein different security constraints are associated with different extracted request patterns; and
sending to a requester a Uniform Resource Locator request to the mapped application program component, thereby providing improved management to administration of computer resources in a stateless web server which are non conformant to rules of a central administration unit.
7. The computer program product as set forth in claim 6 wherein the mapping is performed by one or more associated servlet filters.
8. The computer program product as set forth in claim 6 wherein different attributes are represented by respective resource locators within the extracted request pattern.
9. The computer program product as set forth in claim 6 wherein the security constraints are stored in a web deployment descriptor disposed in computer storage memory.
10. The computer program product as set forth in claim 8 wherein security constraints for each attribute are stored in a web deployment descriptor disposed in computer storage memory.
11. A system for controlling fine-grained security access to managed resources in a stateless web server architecture comprising:
a computer processor;
a computer-readable, storage memory device communicably disposed to the computer processor; and
program instructions embodied by the computer-readable, storage memory device for causing the computer processor to perform steps comprising:
in a stateless web server:
extracting a request pattern from a valid relative path portion of a validly-formatted Uniform Resource Locator request;
mapping at least a portion of the extracted request pattern to one or more application program components;
responsive to the mapping, performing security access to the one or more application program components according to one or more associated security constraints, wherein at least one security constraint comprises at least a portion of the extracted request pattern, and wherein different security constraints are associated with different extracted request patterns; and
sending to a requester a Uniform Resource Locator request to the mapped application program component, thereby providing improved management to administration of computer resources in a stateless web server which are non conformant to rules of a central administration unit.
12. The system as set forth in claim 11 wherein the mapping is performed by one or more associated servlet filters.
13. The system as set forth in claim 11 wherein different attributes are represented by respective resource locators within the extracted request pattern.
14. The system as set forth in claim 11 wherein the security constraints are stored in a web deployment descriptor disposed in computer storage memory.
15. The system as set forth in claim 13 wherein security constraints for each attribute are stored in a web deployment descriptor disposed in computer storage memory.
