Stateless core service transaction patterns

A computer-implemented method comprising:

• initiating a temporary proxy state in a connection handler upon receipt at the connection handler from a client machine of a service request for a service provided by a service provider connected to the connection handler by a backend connection, the connection handler being implemented on one or more processors, the temporary proxy state being specific to the client machine and to the service request;
• passing the service request from the connection handler to the temporary proxy state;
• opening a first connection over the backend connection to the service provider from the connection handler to request fulfillment of the service request;
• populating the temporary proxy state with a copy of original content received at the connection handler from the service provider via the first connection, the original content relating to fulfillment of the service request, the populating comprising creating a temporary proxy state content in the temporary proxy state;
• tagging the original content object on the service provider with an activity indicator that specifies that the original content has been accessed by the connection handler;
• terminating the first connection between the connection handler and the service provider;
• providing at the client machine access to the temporary proxy state content in the temporary proxy state subsequent to the termination of the first connection for fulfillment of the service request, including changing the temporary proxy state content after the first connection is closed and before another connection between the connection handler and the service provider is opened to enable modification of the original content at the service provider to conform to the changed temporary proxy state content;
• and
• in response to receiving a service request completion notification at the connection handler, opening the other connection to the service provider and passing information regarding the changing of the temporary proxy state via the other connection to modify the original content at the service provider to conform to the changed temporary proxy state content, the other connection configured to be terminated in response to a command to terminate the connection.

A system comprising:

• a memory that stores instructions in a machine readable language;
• and
• one or more processors that access the memory and execute the instructions to implement a connection handler comprising an interface accessible by a client machine, a proxy, and a back end connection to a service provider;
• the connection handler performing operations comprising:
• initiating a temporary proxy state upon receipt at the connection handler from the client machine of a service request for a service provided by the service provider, the temporary proxy state being specific to the client machine and to the service request;
• passing the service request to the temporary proxy state;
• opening a first connection over the backend connection to the service provider from the connection handler to request fulfillment of the service request;
• populating the temporary proxy state with a copy of original content received at the connection handler from the service provider via the first connection, the original content relating to fulfillment of the service request, the populating comprising creating a temporary proxy state content in the temporary proxy state;
• tagging the original content object on the service provider with an activity indicator that specifies that the original content has been accessed by the connection handler;
• terminating the first connection between the connection handler and the service provider;
• providing at the client machine access to the temporary proxy state content in the temporary proxy state subsequent to the termination of the first connection for fulfillment of the service request, including changing the temporary proxy state content after the first connection is closed and before another connection between the connection handler and the service provider is opened to enable modification of the original content at the service provider to conform to the changed temporary proxy state content;
• and
• in response to receiving a service request completion notification at the connection handler, opening the other connection to the service provider and passing information regarding the changing of the temporary proxy state via the other connection to modify the original content at the service provider to conform to the changed temporary proxy state content, the other connection configured to be terminated in response to a command to terminate the connection.
