HTTP Keep-Alive

HTTP Keep-Alive is a mechanism for processing multiple HTTP requests and responses over a single TCP connection in HTTP communication.

Between a Device and the Soracom Harvest Data / Files Entry Point

The Harvest Data / Files HTTP entry point supports HTTP Keep-Alive. If the device uses HTTP/1.1, HTTP Keep-Alive is enabled by default with a timeout of 65 seconds.

If you prefer not to use HTTP Keep-Alive, you can disable it in one of two ways:

Set the Connection: close header when the device sends an HTTP request.
Close the TCP connection immediately after receiving the response.

The default timeout value may change without notice.
