(Node.js) HTTPS Requests over Squid Proxy Direct TLS Connection

Demonstrates how to send HTTP requests through an HTTP proxy that supports Direct TLS Connections. (Chilkat tests with a squid 4.11 proxy.)

A direct TLS connection to an HTTP proxy is where the initial connection to the proxy server is TLS.

Note: This example requires Chilkat v9.5.0.83 or greater.

    var http = new chilkat.Http();

    // Set the HTTP proxy domain or IP address.
    http.ProxyDomain = "172.16.16.46";

    // (we use a Squid Cache: Version 4.11 for testing)

    // All requests sent on the http object will now go through the proxy.
