Takeaways:

A simple Perl socket program, SocketRequestResponseBinary.pl, can be used to send both HTTP and SOAP requests to remote servers.
Very few Web servers support HTTP 1.0 as of 2009.
HTTP 1.1 request requires a the "Host" header line.
www.xmlme.com provides a public Web service, GetSpeech, that supports both SOAP 1.1 and SOAP 1.2.
The "Content-Length" header line must provides the exact number of bytes in the request content. This is very important.
The binmode() function should be used to read files in binary mode to avoid \r\n to \n conversion.
