Proxy Support

[jlamhp]

In certain environments, proxy support is needed to allow communication to the cloud, as even direct connections over 443 may be blocked.

There was a pull request in the v1 client that added this but it has never been merged (aws/aws-iot-device-sdk-cpp#9).

[jlamhp]

Changed request a bit. Ideally proxy support would be made available for both MQTT and websockets, as one may be able to tunnel through the proxy over 443 for MQTT.

Web sockets and proxies are now fully supported. Check the samples in aws-crt-cpp/samples/mqtt-pub-sub for more info.

Is it possible to use proxy with MTLS?

[bretambrose]

We are targeting mid April for support for mtls-based mqtt through a tunneling http proxy.

[kkozachuk]

For MTLS-http proxy, will it be SDK-only changes, or datacenters should be updated too? Does mid-April include time for datacenters update, like US-WEST-2?

[bretambrose]

Only the SDK will need updated

Hi @bretambrose . For MTLS-http proxy, is this commit 52627fe you were talking about?

[bretambrose]

No that is some related, preliminary work for different proxy authentication schemes and strategies.

The current "beta" branch for mqtt-through-http-proxy via mtls is here: https://github.com/aws/aws-iot-device-sdk-cpp-v2/tree/ExperimentalProxyv2

@bretambrose Any plans on merging ExperimentalProxyv2 branch with MTLS-http proxy? I remember the plan was on mid-April, are there any changes?

[bretambrose]

The last of the proxy updates were merged into main and released last week.
