(PHP ActiveX) 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.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// Set the HTTP proxy domain or IP address.
$http->ProxyDomain = '172.16.16.46';
// The proxy port..
$http->ProxyPort = 3128;

// Indicate that we are to use a direct TLS connection with the HTTP proxy
// (we use a Squid Cache: Version 4.11 for testing)
$http->ProxyDirectTls = 1;

// If the proxy requires a login or password, we can set it here.
// Otherwise comment out these lines.
$http->ProxyLogin = 'myProxyLogin';
$http->ProxyPassword = 'myProxyPassword';

// All requests sent on the http object will now go through the proxy.
// Give it a test:
$s = $http->quickGetStr('https://www.chilkatsoft.com/helloWorld.html');
if ($http->LastMethodSuccess == 0) {
    print $http->LastErrorText . "\n";
    exit;
}

// The LastErrorText property also contains information when method call succeeds.
// Have a look to see that the request was sent through the proxy:
print $http->LastErrorText . "\n";

print '---' . "\n";
print $s . "\n";
print '---' . "\n";
print 'Success for TLS destination over direct TLS HTTP proxy.' . "\n";
