10 * This demonstrates a minimal http client using secure streams api.
11 *
12 * It visits https://warmcat.com/ and receives the html page there.
13 *
14 * This example is built two different ways from the same source... one includes
15 * the policy everything needed to fulfil the stream directly.  The other -client
16 * variant has no policy itself and some other minor init changes, and connects
17 * to the -proxy example to actually get the connection done.
18 *
19 * In the -client build case, the example does not even init the tls libraries
20 * since the proxy part will take care of all that.
