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

*
* On your local machine, you can run a SOCKS5 proxy like this
*
* $ ssh -N -D 0.0.0.0:1080 localhost -v
*
* If enabled, this also fetches a remote policy that also
* specifies that all traffic should go through the remote
* proxy.
