Code for POST overload

The code as printed throws a ProtocolViolationException on the line ending in
'httpRequest.GetRequestStream())' because the Method property of the httpRequest object is set to GET.

This is fixed by adding 'httpRequest.Method = "POST"' anywhere between the initialization of the
httpRequest object and the offending line.

2nd paragraph under "Discussion" heading

The code snippet does not match the program on the previous page. The snippet creates an XPathDocument
from a MemoryStream object. The complete program creates an XPathDocument from a StringReader object.

The text above the code matches the snippet, which means it is also incorrect (assuming the complete
program on the previous page is correct.)

7th line

I think you forgot to define _syncRoot. I'm not finshed with testing the code, but I defined it as:

private object _syncRoot;

and then assigned the value in the "MyTcpServer" constructor, like

_syncRoot = this;
