Keep-alive connection lifetime #2077
|
Is there are way to set max lifetime of the keep-alive connection? For example, such setting may be helpful for clien-side loadbalancing in k8s, i.e. if connections got closed and opened again after some time they will end up in connecting to different instances of requested service. |

Example of such setting in akka-http https://doc.akka.io/docs/akka-http/current/common/timeouts.html#connection-lifetime-timeout |

I've escalated it into an issue, since it looks like it's not covered in the docs right now. You can control the keep alive expiry like this... limits = httpx.Limits(keepalive_expiry=30.0)
client = httpx.Client(limits=limits)Thanks for the feedback - really great prompt to help us document this. |

Having keepalive_expiry documented will be great, but it looks like this setting controls a bit different thing from one I'm looking for: it controls how long keep-alive connection can be in idle state, while I'm looking for a way to close keep-alive connection even if it's actively used but only after some specified period of time, i.e. I want connection to be closed in 10 seconds after it was established no matter what. |

Is this the sort of thing you mean?... # Connections older than 60 seconds should *always* close as soon as they're idle.
limits = httpx.Limits(max_connection_lifespan=60.0) # This setting doesn't actually exist
client = httpx.Client(limits=limits)We don't have any support for that, and I'm not sure? if we'd want to consider it or not at this point in time. Hints... |

Yes, this is exactly the setting I'm looking for. I'll probably try to inject this behavior from my code to httpx. Looks like it's rarely used feature. |

Great. If you make progress with it then please do let us know how you get on. |

See issue https://github.com/encode/httpx/issues/2079 to track this.
