Use Socket Object for the Connection

See more REST Examples

The Chilkat Socket API provides many features for establishing connections, which includes the following:

• Connect through an HTTP proxy
• Connect through a SOCKS proxy
• Connect through an SSH tunnel
• Binding to a local IP address
• Client-side Certificates (two-way SSL/TLS)
• Public Key Pinning for TLS connections
• Controlling TLS ciphers

Rather than reproducing all of the properties and methods required for these features, the REST object can use a Socket object's connection by calling the UseConnection method. This allows for an application to use the features of the Socket API to establish the connection, and then use it from the REST API.
