The Secret Message Hidden in Every HTTP/2 Connection

November 30th, 2015

Via: jgc:

If you spy on an HTTP/2 connection starting up you’ll notice that it sends an almost-but-not-quite valid HTTP request at the very start of the connection…

Written a little more clearly that’s:

PRI * HTTP2.0

SM

The HTTP verb is PRI and the body contains just SM. Put them together and you get… PRISM.
