Why don't you re-write it such that the SQL call is not even *made*
unless the header is present?

Essentially what I did by using the header *alone* to select a router.
The *transport* asociated with that router made the SQL call.

Or NOT.

It is still a logical AND. Just displaced in time.

Simpler code.

Easier debug, path alteration, general maintenance

Fewer demands on resources.

*many years* of stable production use.

BTW ..

Not to put too fine a point on it - but is it guaranteed all of the time
that there will *exist* the werewithal to feed both parts of the test?

Or might there be cases where either the header is absent or there is no
matching SQL record - or BOTH?

... when a clause goes unresolvable, the machinery tends to natter on
about curly braces when that is not the real issue...
