Re: duplicate calls to web service

["Kim Gibson" <kgibson@xxxxxxxxxxxxxxxxxx>]

Hi Scott,

I've got a call in to the web services tech support people to see if we
can track down the issue with the response. Apparently when they receive
a request, they generate a report of prescription data that is available
to our Underwriting department on the web service company's internet
site. Even when my requests with a 10-minute timeout do not get a
response, the prescription data report is generated. So obviously they
are receiving my requests. 

I'm sure that it's nothing to do with HTTPAPI, but I really appreciate
your help and feedback in tracking these problems down. I've started
creating a separate debug file for each request so I can see exactly
what goes on. Sometimes the response is received, sometimes it isn't.
Hopefully the tech support people will call me soon & we can get this
resolved.

HTTPAPI has been invaluable to me. I'm an RPGILE/CLLE novice (duh) who
loves the iSeries, and being able to consume web services from the
iSeries so easily is way, way cool. Thanks!

Kim
