No events in the dashboard when using proxy, 'Document Moved' messages in the log
I am having trouble using the SDK behind a proxy (in a docker container).
If using a proxy url like http://proxyfqdn:3128 in appInsights.defaultClient.config.proxyHttpUrl and appInsights.defaultClient.config.proxyHttpsUrl I am receiving the following log entries (after activating internal logging):
ApplicationInsights:CorrelationIdManager [ { method: 'GET', disableAppInsightsAutoCollection: true } ]
ApplicationInsights:Sender [ { method: 'POST',
withCredentials: false,
headers:
{ 'Content-Type': 'application/x-json-stream',
'Content-Encoding': 'gzip',
'Content-Length': 635 } } ]
ApplicationInsights:Sender [ '<head><title>Document Moved</title></head>\n<body><h1>Object Moved</h1>This document may be found <a HREF="https://dc.services.visualstudio.com/v2/track">here</a></body>' ]
As I understand it, there was once a change from http to https (see https://github.com/Microsoft/ApplicationInsights-node.js/issues/196#issuecomment-284798465), but even explicitly setting
appInsights.defaultClient.config.endpointUrl = "https://dc.services.visualstudio.com/v2/track";
makes no difference.
I would appreciate any advice how to solve this. I have to use a proxy and can't use http(s)_proxy environment variables because of other libraries breaking for internal calls (since they don't support no_proxy).
@petersendev Does your proxy support https requests in general? What happens if you try a test request using your proxy to a server that only responds on HTTPS, such as https://tls-v1-2.badssl.com:1012/
From a first glance, it seems that the actual protocol (http vs https) is getting lost, either between this SDK and your proxy, or your proxy and the outer internet.
