mbed_official 66:ce8709d9912c 25 * \brief An example TLS Client application
Janos Follath 0:fc70c47eecb4 26 *
mbed_official 66:ce8709d9912c 27 * This application sends an HTTPS request to os.mbed.com and searches
mbed_official 66:ce8709d9912c 28 * for a string in the result.
mbed_official 66:ce8709d9912c 29 *
mbed_official 66:ce8709d9912c 30 * This example is implemented as a logic class (HelloHttpsClient) wrapping a
mbed_official 66:ce8709d9912c 31 * TCP socket. The logic class handles all events, leaving the main loop to just
mbed_official 66:ce8709d9912c 32 * check if the process has finished.
