(CkPython) 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.

import sys

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

http = chilkat.CkHttp()

# Set the HTTP proxy domain or IP address.
http.put_ProxyDomain("172.16.16.46")
# The proxy port..
http.put_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.put_ProxyDirectTls(True)

# If the proxy requires a login or password, we can set it here.
# Otherwise comment out these lines.
http.put_ProxyLogin("myProxyLogin")
http.put_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.get_LastMethodSuccess() == False):
    print(http.lastErrorText())
    sys.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())
