Richard,
Theres a way to transfer huge data using chunked data transfer from
HTTP 1.1 spec. Best way to look for info is online doc "HTTP Made Easy"
at http://www.jmarshall.com/easy/http/
there you see that you can use this to transfer huge data. Hope this
help. I'll quote the doc:
If a server wants to start sending a response before knowing its total
length (like with long script output), it might use the simple chunked
transfer-encoding, which breaks the complete response into smaller
chunks and sends them in series. You can identify such a response
because it contains the "Transfer-Encoding:Êchunked" header. All
HTTPÊ1.1 clients must be able to receive chunked messages.
A chunked message body contains a series of chunks, followed by a line
with "0" (zero), followed by optional footers (just like headers), and
a blank line. Each chunk consists of two parts:
¥ a line with the size of the chunk data, in hex, possibly followed
by a semicolon and extra parameters you can ignore (none are currently
standard), and ending with CRLF.
¥ the data itself, followed by CRLF.
So a chunked response might look like the following:
HTTP/1.1 200 OK
Date: Fri, 31 Dec 1999 23:59:59 GMT
Content-Type: text/plain
Transfer-Encoding: chunked
1a; ignore-stuff-here
abcdefghijklmnopqrstuvwxyz
10
1234567890abcdef
0
some-footer: some-value
another-footer: another-value
[blank line here]
cheers
