Abstract

A server issues a virtual directory name at the beginning of a session, and a client redirects to a page at or below the virtual directory name. The server changes the virtual directory name to a physical name during the tracking in the session, and implements a method to a resource specified by the physical directory name. If necessary, the server identifies the user having an access under the virtual directory name when implementing the method. When the user moves within the physical directory structured to be present at or below the virtual directory (that is, during the session management), the user moves from one link to another by a relative path.

Claims

1. A session managing method for performing processing to a resource on a network, comprising:

a step of receiving a request for said processing from a user system;

a step of deciding whether a virtual directory name is included in a resource which is to be an object of said request;

a step of replacing the virtual directory name with a physical directory name recorded in association with the virtual directory name on condition that the virtual directory name is decided as being included in said deciding step; and

a step of sending a result of said processing to the resource replaced by the physical directory name back to the user system as a response,

wherein, if necessary, one or both of user identification information and session identification information recorded in association with the virtual directory name are referred to for generating the response.

2. The session managing method according to claim 1, further comprising, prior to said step of receiving a request for said processing from a user system, a step of starting a session in response to a request from the user system, wherein said session starting step includes:

a step of issuing a virtual directory name;

a step of recording, by associating one with another, one or both of the session identification information and the user identification information, the virtual directory name, and a physical directory name having recorded a resource that should respond to the request for starting the session;

a step of replacing the physical directory name with the virtual directory name; and

a step of generating a response including location information of the resource replaced by the virtual directory name,

wherein the user system having received the response including the location information redirects to the resource specified by the location information.

5. The session managing method according to claim 1, wherein the virtual directory name uniquely represents one particular user system during a predetermined effective period.

6. The session managing method according to claim 1, wherein a direct access from an outside to the resource under the physical directory name is restricted.

3. A session managing method for performing processing to a resource on a network, comprising:

a step of receiving a request for said processing from a user system;

a step of deciding whether a virtual directory name is included in a resource which is to be an object of said request;

a step of replacing the virtual directory name with a physical directory name recorded in association with the virtual directory name if the virtual directory name is decided as being included in said deciding step;

a step of appending a cookie to the request, said cookie varying with each user system and being recorded in association with the virtual directory name;

a step of sending the request having the resource thereof being replaced by the physical directory name and appended with the cookie to a server holding the resource;

a step of receiving a response to the request from the server;

a step of updating the cookie when the response includes a request to rewrite the cookie; and

a step of sending the response to the user system.

4. The session managing method according to claim 3, further comprising, prior to said step of receiving a request for said processing from a user system, a step of starting a session in response to a request from the user system, wherein said session starting step includes:

a step of issuing a virtual directory name;

a step of generating the cookie that varies with each user system in association with the virtual directory name;

a step of replacing the physical directory name having recorded a resource that should respond to the request if the session is started with the virtual directory name; and

a step of generating a response including location information of the resource replaced by the virtual directory name,

wherein the user system having received the response including the location information redirects to the resource specified by the location information.

7. The session managing method according to claim 3, wherein link information included in the resource under the physical directory name is written by using a relative path.

8. A session managing system for performing processing to a resource on a network, comprising:

means for receiving a request for said processing from a user system;

means for deciding whether a virtual directory name is included in a resource which is to be an object of said request;

means for replacing the virtual directory name with a physical directory name recorded in association with the virtual directory name if said deciding means decides that the virtual directory name is included; and

means for sending a result of said processing to the resource replaced by the physical directory name back to the user system as a response,

wherein, if necessary, one or both of user identification information and session identification information recorded in association with the virtual directory name are referred to for generating the response.

9. The session managing system according to claim 8, further comprising means for starting a session in response to a request from the user system, wherein said session starting means includes:

means, for issuing a virtual directory name other than an already issued virtual directory name;

means for recording, by associating one with another, one or both of the session identification information and the user identification information, the virtual directory name, and a physical directory name having recorded a resource that should respond to the request for starting the session;

means for replacing the physical directory name with the virtual directory name; and

means for generating a response including location information of the resource replaced by the virtual directory name,

wherein the user system having received the response including the location information redirects to the resource specified by the location information.

14. The session managing system according to claim 8, wherein link information included in the resource under the physical directory name is written by using a relative path.

10. A session managing system for performing processing to a resource on a network, comprising:

means for receiving a request for said processing from a user system;

means for deciding whether a virtual directory name is included in a resource which is to be an object of said request;

means for replacing the virtual directory name with a physical directory name recorded in association with the virtual directory name if said deciding means decides that the virtual directory name is included;

means for appending a cookie to the request, said cookie varying with each user system and being recorded in association with the virtual directory name;

means for sending the request having the resource thereof being replaced by the physical directory name and appended with the cookie to a server holding the resource;

means for receiving a response to the request from the server;

means for updating the cookie when the response includes a request to rewrite the cookie; and

means for sending the response to the user system.
