It would be very useful to me for the total results count to be included. I would like to display the total matches (even if I don't retrieve and parse them all).
Can it be added without mucking up everyone else's JSON result parsing though?
For now I have settled for using the XML, but I'd prefer using the shorter JSON format.
It would also be useful for me to have the content length HTTP header variable set (a pedant could argue that it is 'netiquette').
The content length header is normally set, for large requests or for compressed responses it might not be set. Can you give us an example of a call you plan to use for which the content lenght is not set? How is your setting of the parameters "maxRows" and "style"?
