I'm using a GPRS modem to upload data from a serial device to a web
server. I've successfully opened an IP socket to do an HTTP GET etc.

Due to the GPRS data charges I need to send as LITTLE data as possible
when uploading.

Here is an example the ASCII characters I will send through the socket:


======
GET /leave.aspx?d=123SADF2K253K345*L45345ERTS6ETC HTTP/1.1
Host: www.mysite.com
User-Agent: Mozilla/4.0
======

Is this the minimal communication using a web server?
Do I need all 3 lines?
Any ideas for shrinking this data?

Many thanks,

Jim.

Requests don't *need* the user-agent information, but many stupid websites
do. You *do* need the hostname and resource request in the GET command,
though.

I'd imagine you'd have more overhead with networking protocols
(handshaking, etc., on data as it passes through) than the request.
