Proxy device that selectively dispatches resource requests
A proxy device receives a resource request from a requestor via a client device. The resource request is associated with a hosted resource, and the hosted resource is associated with a version-control tag. The proxy device determines, based on the version-control tag, information indicating a current state of the hosted resource. The proxy device obtains user management information associated with the requestor, and conditionally dispatches a processed resource request from the proxy device to a resource host based, at least in part, on the current state of the hosted resource and the user management information.
1. A method comprising:
receiving from a requestor via a client device, at a proxy device, a resource request associated with a hosted resource, wherein the hosted resource is associated with a version-control tag;
determining, by the proxy device, based on the version-control tag, information indicating a current state of the hosted resource;
obtaining, by the proxy device, user management information associated with the requestor; and
conditionally dispatching a processed resource request from the proxy device to a resource host based, at least in part, on the current state of the hosted resource and the user management information.
2. The method of claim 1 , further comprising:
dispatching the processed resource request from the proxy device to a resource host in response to determining that the requestor is permitted access to resources having a state matching the current state of the hosted resource.
3. The method of claim 2 , further comprising:
wherein multiple instances of the hosted resource exist, including a primary instance of the hosted resource;
determining by the proxy device, an alias to the primary instance;
generating the processed resource request to include information indicating the primary instance; and
dispatching the processed resource request from the proxy device to the resource host.
4. The method of claim 1 , wherein:
the version-control tag includes information indicating that a single instance of the hosted resource exists.
5. The method of claim 1 , further comprising:
discarding the resource request in response to determining that the requestor lacks permissions to access resources having a state matching the current state of the hosted resource.
6. The method of claim 1 , further comprising:
transmitting an error notification from the proxy device to the client device in response to determining that the requestor lacks permissions to access resources having a state matching the current state of the hosted resource.
7. The method of claim 1 , wherein:
the information indicating a current state of the hosted resource includes information specifying one or more states selected from the group consisting essentially of “Available,” “Running,” “Offline,” “Busy,” and “Working-Copy”.
8. A proxy device comprising:
a communications interface configured to receive from a requestor via a client device, a resource request associated with a hosted resource, wherein the hosted resource is associated with a version-control tag;
a processor configured to implement a request handling module, the request handling module configured to:
determine, based on the version-control tag, information indicating a current state of the hosted resource;
obtain user management information associated with the requestor; and
conditionally dispatch a processed resource request from the proxy device to a resource host based, at least in part, on the current state of the hosted resource and the user management information.
9. The proxy device of claim 8 , wherein the request handling module is further configured to:
dispatch the processed resource request from the proxy device to a resource host in response to determining that the requestor is permitted access to resources having a state matching the current state of the hosted resource.
10. The proxy device of claim 9 , wherein:
multiple instances of the hosted resource exist, including a primary instance of the hosted resource;
the request handling module is further configured to:
obtain an alias to the primary instance;
generate the processed resource request to include information indicating the primary instance; and
dispatch the processed resource request from the proxy device to the resource host.
11. The proxy device of claim 8 , wherein:
the version-control tag includes information indicating that a single instance of the hosted resource exists.
12. The proxy device of claim 8 , wherein the request handling module is further configured to:
discard the resource request in response to determining that the requestor lacks permissions to access resources having a state matching the current state of the hosted resource.
13. The proxy device of claim 8 , wherein the request handling module is further configured to:
transmit an error notification from the proxy device to the client device in response to determining that the requestor lacks permissions to access resources having a state matching the current state of the hosted resource.
14. The proxy device of claim 8 , wherein:
the information indicating a current state of the hosted resource includes information specifying one or more states selected from the group consisting essentially of “Live,” “Pending_Approval,” “Beta,” and “Head”.
15. A non-transitory computer readable medium tangibly embodying a program of instructions to be executed by a processor, the program of instructions comprising:
at least one instruction to receive from a requestor via a client device, at a proxy device, a resource request associated with a hosted resource, wherein the hosted resource is associated with a version-control tag;
at least one instruction to determine, by the proxy device, based on the version-control tag, information indicating a current state of the hosted resource;
at least one instruction to obtain, by the proxy device, user management information associated with the requestor; and
at least one instruction to conditionally dispatch a processed resource request from the proxy device to a resource host based, at least in part, on the current state of the hosted resource and the user management information.
16. The non-transitory computer readable medium of claim 15 , wherein the program of instructions further comprises:
at least one instruction to dispatch the processed resource request from the proxy device to a resource host in response to determining that the requestor is permitted access to resources having a state matching the current state of the hosted resource.
17. The non-transitory computer readable medium of claim 16 , wherein:
multiple instances of the hosted resource exist, including a primary instance of the hosted resource;
and the program of instructions further comprises:
at least one instruction to determine by the proxy device, an alias to the primary instance;
at least one instruction to generate the processed resource request to include information indicating the primary instance; and
at least one instruction to dispatch the processed resource request from the proxy device to the resource host.
18. The non-transitory computer readable medium of claim 15 , wherein:
the version-control tag includes information indicating that a single instance of the hosted resource exists.
19. The non-transitory computer readable medium of claim 15 , wherein the program of instructions further comprises:
at least one instruction to discard the resource request in response to determining that the requestor lacks permissions to access resources having a state matching the current state of the hosted resource.
20. The non-transitory computer readable medium of claim 15 , wherein the program of instructions further comprises:
at least one instruction to transmit an error notification from the proxy device to the client device in response to determining that the requestor lacks permissions to access resources having a state matching the current state of the hosted resource.
