Description

Trying to connect to SignalR Hub through the nodejs client via a Proxy. The connection doesn't work with a corporate proxy. What should I put in options(aka IHttpConnectionOptions) in my nodejs client to get it to work ?

const signalR = require('@microsoft/signalr'); var url = require('url'); var HttpsProxyAgent = require('https-proxy-agent'); var agent;

// HTTP/HTTPS proxy to connect to var proxy = process.env.http_proxy; if (proxy) { var options = url.parse(proxy); agent = new HttpsProxyAgent(options); } let options = { accessTokenFactory: pcsUtils.getJwtToken, Proxy: agent//???????????? } connection = new signalR.HubConnectionBuilder() .withUrl(hubUrl, options) .build(); It works without the proxy.

TIA,

Research direction
Investigate the JavaScript SignalR client code in the aspnetcore repository (https://github.com/dotnet/aspnetcore), specifically the @microsoft/signalr package. Look for any existing proxy support or options for IHttpConnectionOptions. The issue may require adding proxy agent support similar to how it's done in other HTTP clients.
