POSTing large amounts of data

[CyberFerret]

Hi all,

As per a client project specs, we are using NetTalk to build a 'front end' to the Amazon S3 service in order to upload very large files to 'the cloud'.

The files we are talking about here are quite huge - some in the order of 100MB, but I believe that we will have a problems with the size of the POST variable?  I am assuming that we are limited by the max size of the STRING data type (4MB)?  What makes this extra tricky is that the file has to be Base64 Encoded as well, so I am not sure of the most efficient method of encoding a large file, then pushing it up to AmazonAWS.

Is there a way of 'chunking' the POSTed data?

Thanks,
Devan
