Header Questions

[Mathew Heard]

Not entirely a Lua question, but I want to request it from Lua (if possible) so yeah :)

Is it possible to get either:

a) The original request headers in a raw form?

or

b) The original request headers in order?

From my understanding of the request parsing process I do not believe this is possible, but please correct me if I am wrong. Hopefully I am.

Just a re-write of the question for clarity:

a) Is r->headers_in ordered by the order received in the request? It does appear to be.

b) Lua Tables with keys are not insert order I hazard. Hence that explains what I am seeing.

Yes, sure:

If you are interested in how it is implemented, just check out the source ;)

Thank you I was not aware of that method :)

Ideally I would have preferred just a format like:

{
{name="Host",value="domain.com"},
{..},
...
}

But I should be able to make that work.
