Whatever it is, it's not about "coding"

If you have a problem like:

  • One of a set of load balanced servers is behaving unexpectedly and
  • Targetting that machine directly by IP address does not fail the same way

Then you may have a missing host header.

Your host name may be being routed to a different application.

This kind of thing has prompted us to think about writing smoke tests for this type of multi-machine configuration.
