[DUG] SOAP pack size

[Kyley Harris]

well to give you an example..

I have an object that represents a customer with about 20 fields of
information... names addresses etc.. I can convert about 5000 to an xml
structure that compressed to a size that takes a couple of seconds on dial
up... I get roughly each 1mb of XML transfers using my protocol at around
40-60k of actual transferred size using a zip compression... for you, using
a webservice, you would need to add an IIS or APache compression layer into
the server, which only works if client and server both have it...

if you don't need to send 300 at a time.. (i wonder is each sales lines
items less than 10 etc) if you might be better to break the job down into a
series of sends, and a batch completion...

How I would do it is to send a SOAP packet which then has one field inside
called DATA.. and data is the compressed zipped transaction data.. your
webservice can open the soap packet and unzip the DATA field with zlib.  you
will find that your 5mb XML transactions are probably only about 100-200k of
filesize zipped.
