I've written and published a basic handler that uses a web service via
Scott's HTTPAPI - a few years old now but the principals remain the same.
http://www.ibmsystemsmag.com/ibmi/developer/general/oa_rpg/ It used my OA
template as the foundation which can save you a lot of time and effort if
you have not written fo OA before. Details here:

Which reminds me - I really must update that to dcl-x data definitions.

Not sure how well you "cache" idea will work unless you can guarantee that
there is never any direct access to the related file. Sound like a problem
waiting to happen.

So we've got a requirement to modify our existing RPG applications so
that
for some users, instead of updating a local Db2 file, we need to make
REST
call to post the data to an external server.

Reads will be from the local Db2 table; though we're planning to cache
the
"update" that was posted to the web service. So that we don't have to
wait
for the data to be replicated back to the i. (We considered a Db
trigger,
but that idea was a no-go. Eventually the READs for some users will also
be pointed to the web service)

Anybody ever done or even considered such a handler?

Any tips/tricks/gotchas you can share?

Thanks,
Charles
