HTTPS Requests over Squid Proxy Direct TLS Connection

See more HTTP Examples

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.

Objective-C

#import <CkoHttp.h>
#import <NSString.h>

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

CkoHttp *http = [[CkoHttp alloc] init];

// Set the HTTP proxy domain or IP address.
http.ProxyDomain = @"172.16.16.46";
// The proxy port..
http.ProxyPort = [NSNumber numberWithInt: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 = YES;

// 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:
NSString *s = [http QuickGetStr: @"https://www.chilkatsoft.com/helloWorld.html"];
if (http.LastMethodSuccess == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// The LastErrorText property also contains information when method call succeeds.
// Have a look to see that the request was sent through the proxy:
NSLog(@"%@",http.LastErrorText);

NSLog(@"%@",@"---");
NSLog(@"%@",s);
NSLog(@"%@",@"---");
NSLog(@"%@",@"Success for TLS destination over direct TLS HTTP proxy.");
