Abstract
A first computing device sends a plurality of request messages to a second computing device that is outside a firewall associated with the first computing device, each request message of the plurality of request messages comprising a request for the second computing device to send a response message to the first computing device after a time period specified in the request message. The first computing device determines a timeout period of the firewall based on one or more response messages that are received responsive to the plurality of request messages. The first computing device sends or receives an additional message to or from the second computing device within the timeout period to prevent the firewall from blocking future messages from the second computing device.
