We are pleased to announce that the extension of the maximum Keep-Alive timeout for Soracom's HTTP entry points to 65 seconds will be rolled out starting from April 7, 2025.

As previously mentioned, by specifying Connection: keep-alive in the HTTP request header, devices using Soracom Air for Cellular and Soracom Arc can reuse TCP connections and reduce data usage due to reconnections when sending additional HTTP requests. With this change, if devices send HTTP requests to these entry points at intervals of less than 65 seconds, the connection will be maintained, and data usage will be reduced. Previously, the Keep-Alive timeout was set to 5 seconds.

Affected Entry Points

• Soracom Beam HTTP Entry Point
• Soracom Beam Website Entry Point
• Soracom Funk HTTP Entry Point
• Soracom Funnel HTTP Entry Point
• Soracom Harvest Data/Files HTTP Entry Point
• Unified Endpoint HTTP Entry Point

Implementation Date

April 7, 2025

This specification change will be reflected gradually after the implementation date.

Required Actions

If your device cannot support the extended Keep-Alive timeout, you can specify Connection: close in the HTTP request header to disable the Keep-Alive timeout.

If you have any questions or concerns, please feel free to contact the Soracom support team.
