Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.

Before you speak the answer, walk the interviewer through these steps:
- 1It should see the
raw request early to apply SSL redirects and refuse bad hosts before other layers do work.
- 2Placing it later can

- 4Give an example
One tiny concrete case you can say aloud.

Key takeaway
It should see the raw request early to apply SSL redirects and refuse bad hosts before other layers do work. Placing it later can waste cycles or leak headers on responses that should have been redirected.
