It is really no way to use GET to pass the data? Actually, I want to pass the data to SAP Bisness Connect, they only provide me a url with querystring (eg: www.abc.com?xml=mydata) to pass my data to them. and my data may be very large, that is y i have to extend the GET characters limit. I am very supprise they (SAP BC) can passing me (large amount of data) by querystring.
