If you read from socket HTTP/1.1 response then you can determine the size of the data from Content-Length header. But be aware of chunked responses, i.e.


Code:
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]

what corresponds to

Code:
HTTP/1.1 200 OK
Date: Fri, 31 Dec 1999 23:59:59 GMT
Content-Type: text/plain
Content-Length: 42
some-footer: some-value
another-footer: another-value

abcdefghijklmnopqrstuvwxyz1234567890abcdef


see RFC 2616
