Body property holds full body of the resource that will
be sent to the server with next request. It will be send
as-is, with no changes. You can access body property
directly to adjust this contents to your needs easily.
If you plan to upload large files, using Body property
directly may not be a good idea, because transferring and
converting from file contents to unicode characters
presented by VB may take time and consume resources - so
choose wisely if it's better to use Body property, or
to read/write file on the disk directly (provided with
Filename
property).
