Title:
RESPONSE DELAY TIME DETERMINATION TO MAINTAIN LONG POLLING CONNECTION
Document Type and Number:
WIPO Patent Application WO/2019/103269
Kind Code:
A1
Abstract:
An image forming apparatus and method for determining a response delay time for maintaining a long polling connection are provided. In an example, the image forming apparatus includes a communication device to communicate with an external device, a processor, and a memory storing instructions executable by the processor. The processor may execute the instructions to request the external device for a response about whether a job to be performed by the image forming apparatus is present based on a response delay time for long polling the external device by the image forming apparatus. The processor may also execute the instructions to detect an error from the response, adjust the response delay time, and determine a final response delay time for maintaining connection of the long polling by re-adjusting the adjusted response delay time based on a result of performing the long polling based on the adjusted response delay time.
