Systems and methods for virtual multiplexed connections

A server proxy for facilitating a plurality of virtual transmission control protocol connections between a target application and an external device, the server proxy comprising:

• a processor;
• and
• a non-transitory computer readable storage medium comprising computer-executable instructions that cause the processor to perform operations comprising:
• receiving an open request from the external device via a stateless protocol, wherein the open request includes a target identifier;
• opening a connection between the server proxy and the target application based on the target identifier;
• providing, via the stateless protocol, an open status response to the external device indicating a status of the open request, wherein the open status response includes a session identifier and a sequence identifier;
• receiving, via the stateless protocol, a data request from the external device including the session identifier and an incremented sequence identifier, the incremented sequence identifier corresponding to the sequence identifier incremented by a predetermined value;
• providing, via the stateless protocol, the data from the received data request to the target application via the connection between the server proxy and the target application
• receiving, via the stateless protocol, a poll instruction from the external device following a predetermined period of time without communication from the external device, the poll request comprising the session identifier and the incremented sequence number incremented by the predetermined value by the external device;
• and
• providing, via the stateless protocol, a poll response.

A client proxy for communicating with a target application, the client proxy comprising:

• a processor;
• and
• a non-transitory computer readable storage medium comprising computer-executable instructions that cause the processor to perform operations comprising:
• providing an open request via a stateless protocol based on a uniform resource locator, wherein the open request includes a target identifier;
• receiving, via the stateless protocol, a response to the open request, the response indicating a status of the open request and including a session identifier and a sequence identifier;
• providing, via the stateless protocol, a data request including the session identifier and an incremented sequence identifier, the incremented sequence identifier corresponding to the sequence identifier incremented by a predetermined value;
• receiving, via the stateless protocol, one or more data responses originating from the target application;
• providing, via the stateless protocol, a poll instruction following a predetermined period of time without communication with the target application, the poll request comprising the session identifier and the incremented sequence number incremented by the predetermined value;
• and
• receiving, via the stateless protocol, a poll response.

A method for performing communications via virtual transmission control protocol connections between a target application within a secured environment and a device external to the secured environment, the method comprising:

• receiving an open request from the external device via a stateless protocol, wherein the open request includes a target identifier;
• opening a stateful connection via a network resource within the secured environment with the target application based on the target identifier;
• providing, via the stateless protocol, a response to the external device indicating a status of the open request, wherein the response includes a session identifier and a sequence identifier;
• receiving, via the stateless protocol, a data request from the external device including the session identifier and an incremented sequence identifier, the incremented sequence identifier corresponding to the sequence identifier incremented by a predetermined value;
• transmitting, via the stateless protocol, data from the received data request to the target application via the stateful connection;
• receiving, via the stateless protocol, a poll instruction from the external device following a predetermined period of time without communication with the target application, the poll request comprising the session identifier and the incremented sequence number incremented by the predetermined value;
• and
• sending, via the stateless protocol, a poll response.
