Okay.  I've looked into this problem some more, and it looks I like I
was mistaken about the cause of the problem.  I've done some dumps of
network traffic, and it turns out that requests are actually using
HTTP/1.1, but that they're malformed.

For example, instead of sending "Host: www.msnbc.com", it sends "host:
www.msnbc.com" (i.e. HTTP headers are being put into lowercase).

In HttpComms::request() in libmyth, we do:

header.setValue("Host", url.host());

with an uppercase header, but somehow it's being converted to lowercase,
presumably in QT's QHttpRequestHeader class.

Is there any way to work around this problem?
