If you are using or thinking about using the wolfSSL lightweight SSL/TLS library in your application or project, it’s oftentimes helpful to get a general overview of some of the terms and types which are used in a simple wolfSSL connection. Below we have included a general summary of these types.1) socket: wolfSSL uses the type SOCKET_T to allow different TCP stacks to be used.2) SSL Context:  wolfSSL uses the type CYASSL_CTX.  This is either a client context or a server context.  Multiple SSL connections can be created from a single CYASSL_CTX.  The context holds CA certificates, keys, and options for the connections that will be created from it.3) SSL Connection:  wolfSSL uses the type CYASSL* to represent a single SSL connection.  This object is created from a parent CYASSL_CTX.  It may contain a SOCKET_T if the underlying I/O is socket based, but that is not a requirement. With wolfSSL’s I/O callbacks a memory buffer, file, or event handler may be used instead. 1) SSL Session:  wolfSSL uses the type CYASSL_SESSION.  Each time a full SSL handshake is done on a CYASSL* Connection object a new CYASSL_SESSION* is created.  A single CYASSL_SESSION* can later be used to do session resumption on multiple different CYASSL* connections.For example, lets say a browser has 3 tabs open to a simple secure site.  The browser would need:1 **CYASSL_CTX*** client context with CA certificates loaded.3 **SOCKET_T** sockets, 1 for each tab.3 **CYASSL*** connections, one for each tab.  Each connection owns one of the 3 unique SOCKET_T but was created from the same CYASSL_CTX*.1 **CYASSL_SESSION*** was created from the first tab.  The 2nd and 3rd tab would use the initial CYASSL_SESSION* to do session resumption with their respective CYASSL* connections.Code wise, to retrieve a session the application would just call ***wolfSSL_get_session****()* before ending the connection with ***wolfSSL_shutdown()***.CYASSL_SESSION* mySession = wolfSSL_get_session(ssl_conn1);To later use that session on a new CYASSL connection (ssl_conn2), do:wolfSSL_set_session(ssl_conn2, mySession);before calling ***wolfSSL_connect()***.  Connection 2 will attempt session resumption.For more detailed information, the wolfSSL API reference discusses each function in more detail: [http://www.yassl.com/yaSSL/Docs-cyassl-manual-17-cyassl-api-reference.html](http://www.yassl.com/yaSSL/Docs-cyassl-manual-17-cyassl-api-reference.html)The wolfSSL example client (examples/client/client.c in the general [wolfSSL download](https://www.wolfssl.com/download/)) does session resumption if the user passes **-r** to the command line.  If you search for **get_session** and **set_session** you should see right where its used.
