This event is fired when you post and receive document
body from/to server. Please note that Total argument may be zero - in which case
wodHttpDLX is unaware of total number of bytes that will
arrive. It depends only on server's
'Content-Length' header if this value is known or
not.
When
Compression property is set, Position and Total
arguments will show size of compressed resource - not original
uncompressed one. This is because wodHttpDLX only knows about
compressed resource size.
If Request.Resume
property is set, Progress event will start at resumed position, not
from 0.
