Session transfer and suspension in a remote access application framework
Systems and method for providing for suspension and transfer of remote access sessions. In accordance with the methods, a request to suspend a session may be received at a server tier. The server tier prepares a URL that may be used at a later time by a client to resume the session. The URL is communicated to a client tier from which the request was received and, thereafter, a connection between the client tier and the server tier is closed. At a subsequent time, a request may be received to resume the session at the URL. After receipt of the request to resume the session, a connection with the requesting client tier is established by the server tier, and the session is resumed.
1. A method of suspending and resuming a remote access session in a tiered framework, comprising:
receiving a request to suspend the session at a server tier;
preparing, at the server tier, a URL to resume the session, the URL being a data structure representing the session, and the URL being used by the server tier to associate a client to the remote access session;
communicating the URL to the client in a client tier; closing a connection at the client tier with the server tier; and
at a subsequent time, receiving a request to resume the session at the URL.
2. The method of claim 1 , further comprising saving application state information with the request.
3. The method of claim 2 , further comprising suspending an application being accessed within the remote access session.
4. The method of claim 2 , further comprising saving application-related information associated with the remote access session.
5. The method of claim 2 , further comprising resuming the session using the application state information.
6. The method of claim 3 , further comprising maintaining the application in a running state in the server tier for a predetermined period of time after receiving the request.
7. The method of claim 3 , further comprising suspending a virtual machine in which an application being accessed is executing.
8. The method of claim 3 , further comprising migrating the application from a first server to a second server.
9. The method of claim 8 , further comprising migrating a virtual machine associated with the application from a first server to a second server.
10. The method of claim 1 , further comprising:
providing a password with the request to suspend; and
authenticating the request to resume the session at the URL using the password.
11. The method of claim 1 , the receiving the request to resume the session at the URL further comprising:
connecting the client tier with the server tier; and
resuming the session.
12. The method of claim 11 , further comprising accessing a saved state model and application-related information to place the application associated with the session into a running state.
13. A method of suspending and resuming a remote access session in a tiered framework, comprising: suspending an application associated with the remote access session at a server tier;
saving at least one of an application state model and application-related information associated with the application;
preparing, at the server tier, a URL to resume the session, the URL being a data structure representing the session, and the URL being used by the server tier to associate a client to the remote access session;
mapping the URL to the application;
and communicating the URL to the client a client tier.
14. The method of claim 13 , further comprising receiving a request to resume the session at the URL.
15. The method of claim 13 , further comprising resuming the session using the at least one of the application state information and application-related information.
16. The method of claim 13 , further comprising suspending a virtual machine in which the application is executing.
17. The method of claim 13 , further comprising migrating the application from a first server to a second server.
18. The method of claim 16 , further comprising migrating the virtual machine associated from a first server to a second server.
19. The method of claim 13 , further comprising:
providing a password to resume the session; and
authenticating the request to resume the session at the URL using the password.
20. A tangible computer readable media containing computer-executable instructions that when executed by a computing device perform a method comprising:
receiving a request from a client tier to suspend an application executing on in a server tier;
suspending the application at a server tier by saving at least one of an application state model and application-related information associated with the application;
preparing a URL to resume a session that is mapped to the application, the URL further representing the session as a data structure used by the server tier to associate a client to the session; and
communicating the URL to the client tier to enable the client tier to resume the application.
