View Full Version : HTTPTransfer woes - VDF10.1

I have a WebApp at a remote site with tables in the same format as at
the home site. I am using HTTPTransfers to retrieve orders from the
remote site and to update inventory and other tables to the remote site.

Today an HTTPTransfer used to update the customer table at the remote
site failed. Specifically, the post transfer does not return a valid
handle.

Looking at the date/time stamp of the .wo file in the WebApp, nothing
has changed since sometime in May. The client-side bpo hasn't changed
since it last worked successfully.

I have used the debugger to step through the client-side BPO and can
find no problem.

I modified the client-side bpo to save an XML file instead of using the
HTTPTransfer. I then modified the WO in the WebApp to read the local
file and, using the debugger, stepped through the process and it works
as expected.

The kicker is that I have other HTTPTransfers in the same client-side
program that work fine. However, I have had to modify these procedures
to send smaller XML objects as there seems to be a size problem either
at either the client or server side. This same modification is in place
in the problem BPO. I'm interested in knowing about any limitations,
but I've worked around that problem for the moment.

I'm stumped as to how to further debug this problem. Can anyone suggest
something?
