Http Header question

Wed Jan 20 12:50:48 EST 2016

If you were doing this from an html form, the file in question would be
uploaded to the server's temp directory and the php script can access it
from there using the "tmp_name" key.  I think the $_FILES array is created
as a result of the  enctype setting.  Not sure how you would replace all
that via LC though.
