NAME

       Net::SSLeay::Handle - Perl module that lets SSL (HTTPS) sockets be handled as standard
       file handles.

SYNOPSIS

         use Net::SSLeay::Handle qw/shutdown/;
         my ($host, $port) = ("localhost", 443);

         tie(*SSL, "Net::SSLeay::Handle", $host, $port);

         print SSL "GET / HTTP/1.0\r\n";
         shutdown(\*SSL, 1);
         print while (<SSL>);
         close SSL;

DESCRIPTION

       Net::SSLeay::Handle allows you to request and receive HTTPS web pages using "old-fashion"
       file handles as in:

           print SSL "GET / HTTP/1.0\r\n";

       and

           print while (<SSL>);

       If you export the shutdown routine, then the only extra code that you need to add to your
       program is the tie function as in:

           my $socket;
           if ($scheme eq "https") {
               tie(*S2, "Net::SSLeay::Handle", $host, $port);
               $socket = \*S2;
           else {
               $socket = Net::SSLeay::Handle->make_socket($host, $port);
           }
           print $socket $request_headers;
           ...

FUNCTIONS

       shutdown
             shutdown(\*SOCKET, $mode)

           Calls to the main shutdown() don't work with tied sockets created with this module.
           This shutdown should be able to distinquish between tied and untied sockets and do the
           right thing.

       debug
             my $debug = Net::SSLeay::Handle->debug()
             Net::SSLeay::Handle->debug(1)

           Get/set debugging mode. Always returns the debug value before the function call.  if
           an additional argument is given the debug option will be set to this value.

       make_socket
             my $sock = Net::SSLeay::Handle->make_socket($host, $port);

           Creates a socket that is connected to $post using $port. It uses
           $Net::SSLeay::proxyhost and proxyport if set and authentificates itself against this
           proxy depending on $Net::SSLeay::proxyauth. It also turns autoflush on for the created
           socket.

   USING EXISTING SOCKETS
       One of the motivations for writing this module was to avoid duplicating socket creation
       code (which is mostly error handling).  The calls to tie() above where it is passed a
       $host and $port is provided for convenience testing.  If you already have a socket
       connected to the right host and port, S1, then you can do something like:

           my $socket \*S1;
           if ($scheme eq "https") {
               tie(*S2, "Net::SSLeay::Handle", $socket);
               $socket = \*S2;
           }
           my $last_sel = select($socket); $| = 1; select($last_sel);
           print $socket $request_headers;
           ...

       Note: As far as I know you must be careful with the globs in the tie() function.  The
       first parameter must be a glob (*SOMETHING) and the last parameter must be a reference to
       a glob (\*SOMETHING_ELSE) or a scaler that was assigned to a reference to a glob (as in
       the example above)

       Also, the two globs must be different.  When I tried to use the same glob, I got a core
       dump.

   EXPORT
       None by default.

       You can export the shutdown() function.

       It is suggested that you do export shutdown() or use the fully qualified
       Net::SSLeay::Handle::shutdown() function to shutdown SSL sockets.  It should be smart
       enough to distinguish between SSL and non-SSL sockets and do the right thing.

EXAMPLES

         use Net::SSLeay::Handle qw/shutdown/;
         my ($host, $port) = ("localhost", 443);

         tie(*SSL, "Net::SSLeay::Handle", $host, $port);

         print SSL "GET / HTTP/1.0\r\n";
         shutdown(\*SSL, 1);
         print while (<SSL>);
         close SSL;

TODO

       Better error handling.  Callback routine?

CAVEATS

       Tying to a file handle is a little tricky (for me at least).

       The first parameter to tie() must be a glob (*SOMETHING) and the last parameter must be a
       reference to a glob (\*SOMETHING_ELSE) or a scaler that was assigned to a reference to a
       glob ($s = \*SOMETHING_ELSE).  Also, the two globs must be different.  When I tried to use
       the same glob, I got a core dump.

       I was able to associate attributes to globs created by this module (like *SSL above) by
       making a hash of hashes keyed by the file head1.
