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.

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

loo_Http = create oleobject
li_rc = loo_Http.ConnectToNewObject("Chilkat.Http")
if li_rc < 0 then
    destroy loo_Http
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// Set the HTTP proxy domain or IP address.
loo_Http.ProxyDomain = "172.16.16.46"
// The proxy port..
loo_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)

// If the proxy requires a login or password, we can set it here.
// Otherwise comment out these lines.
loo_Http.ProxyLogin = "myProxyLogin"

// All requests sent on the http object will now go through the proxy.
// Give it a test:
s = loo_Http.QuickGetStr("https://www.chilkatsoft.com/helloWorld.html")
if loo_Http.LastMethodSuccess = 0 then
    Write-Debug loo_Http.LastErrorText
    destroy loo_Http
    return
end if

// The LastErrorText property also contains information when method call succeeds.
// Have a look to see that the request was sent through the proxy:
Write-Debug loo_Http.LastErrorText

Write-Debug "---"
Write-Debug s
Write-Debug "---"
Write-Debug "Success for TLS destination over direct TLS HTTP proxy."
