Connect to twitter.com and copies this webpage to a file.
Dependencies: EthernetInterface3 HTTPSClient TLS_axTLS mbed-rtos mbed
This example shows how to use the HTTPSClient library by copying the content of this webpage to a file. Before running this program, you must download these certificates and copy them to the mbed. After running this program, a file called index.htm has been created and you can open it with your favorite browser to display the webpage the mbed have just downloaded.
