Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server. DataFlex

Use ChilkatAx-win32.pkg

Procedure Test
    Boolean iSuccess
    Handle hoSocket
    String sHostname
    Boolean iSsl

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

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to calling Connect.  The connection may be SSL/TLS or 
    // non-secure - both will work with a SOCKS proxy.
    // The SOCKS hostname may be a domain name or 
    // IP address:
    Set ComSocksHostname Of hoSocket To "www.mysocksproxyserver.com"

    // of the SOCKS proxy server:
    Set ComSocksVersion Of hoSocket To 5
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.
