New Revision: 1782180

URL: http://svn.apache.org/viewvc?rev=1782180&view=rev
Log:
Merge r1782140 from trunk:

Add debugging info to the HttpProtocolOption directive doc

In bugzilla and users@ we keep receiving questions about
how to test the new restrictions imposed by HttpProtocolOptions.
Added some info about how to use openssl s_client properly
and the mod_dumpio's directives to debug (thanks to
Daniel Ferradal for this suggestion).
