' The PUT request to be sent will look like this:

' PUT /request HTTP/1.1
' Content-Type: application/jsonrequest
' Cookie: JSESSIONID=1234
' Content-Encoding: identity
' Host: json.penzance.org
' Accept: application/jsonrequest
' Accept-Encoding:
' Content-Length: 72
' 
' {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

' First, remove default header fields that would be automatically
' sent.  (These headers are harmless, and shouldn't need to 
' be suppressed, but just in case...)

http.UserAgent = ""
http.AcceptLanguage = ""

' Suppress the Accept-Encoding header by disallowing 
' a gzip response:
http.AllowGzip = 0

' If a Cookie needs to be added...
http.SetRequestHeader "Cookie","JSESSIONID=1234"

' Add the Content-Encoding: identity header.
http.SetRequestHeader "Content-Encoding","identity"

' Modify the default "Accept" header:
http.Accept = "application/jsonrequest"
