Simon Fell:
SOAP 1.2 changes the content-type from text/xml to
application/soap+xml, unfortuantly this doesn't play well with the
new GET binding, IE now prompts me to save/open the file, rather
than just displaying the XML, this makes testing the GET binding
from a browser a pain. Try
HKEY_CLASSES_ROOT\MIME\Database\Content Type ? Otherwise,
this
draft suggests where to send feedback.
