There's a little paragraph explaining this behavior in the middle of p.
119 of my book. It was asked so often in the 1st Ed I added it to the
2nd Ed. http://www.servlets.com/jservlet2/ for more info on the book.
Summarizing a paragraph down into a sentence: the server may sever the
connection to protect itself from reading the upload, and the client may
not read the server's error page sent before the severing.
