SCGI - for implementing an SCGI interface for an application server

  use SCGI;
  use IO::Socket;
  
  my $socket = IO::Socket::INET->new(Listen => 5, ReuseAddr => 1, LocalPort => 8080)
    or die "cannot bind to port 8080: $!";
  
  my $scgi = SCGI->new($socket, blocking => 1);
  
  while (my $request = $scgi->accept) {
    $request->read_env;
    read $request->connection, my $body, $request->env->{CONTENT_LENGTH};
    # 
    print $request->connection "Content-Type: text/plain\n\nHello!\n";
  }

Takes a socket followed by a set of options (key value pairs) and returns a new SCGI listener. Currently the only supported option is blocking, to indicate that the socket blocks and that the library should not treat it accordingly. By default blocking is false. (NOTE: blocking is now a named rather than positional parameter. Using as a positional parameter will produce a warning in this version and will throw an exception in the next version).
Accepts a connection from the socket and returns an "SCGI::Request" for it.
Returns the socket that was passed to the constructor.
Returns true if it was indicated that the socket should be blocking when the SCGI object was created.

The SCGI Apache2 module had a bug (for me at least), which resulted in segmentation faults. This appeared after version 1.2 (the version in Debian Sarge) and was fixed in 1.10.

The SCGI Apache2 module has a bug where certain headers can be repeated. This is still present in version 1.10. A patch has been accepted and this issue should be resolved in the next release. This modulenow issues a warning on a repeated header, rather than throwing an exception as in the previous version.
