// This example gets an URL using http.Get().  URL scheme can be http or https.
//
// Note: It may be necessary to increase the stack size when using "net/http".
// Use the -stack-size=4KB command line option.
//
// Some targets (Arduino Nano33 IoT) don't have enough SRAM to run http.Get().
// Use the following for those targets:
//
//     examples/net/webclient (for HTTP)
//     examples/net/tlsclient (for HTTPS)
