customers was experiencing the problem and decided to get Microsoft on
the job. Armed with information we provided, they appear to have been
able to get Microsoft to reconfigure their server to work "properly".

Last night this is what we got:

Notice the "Transfer-Encoding: chunked". That breaks things.

This morning we get:

Our customer reports the site to now be accessible.
