Prevent header renaming?

[mhenrixon]

How can I prevent header renaming? I need to provide headers with an underscore and I can't find a way to achieve this.

Can you explain why you might need this?

[ixti]

You're not the first one who was asking this question, so I'm pretty concerned if this is really needed feature (we can probably allow pass header names without normalization)

[mhenrixon]

For me it turned out it wasn't needed I just thought it was when I got different errors from CURL when I changed the name of the headers.

Ah. OK. Thanks.

I think in general the way we process headers could use some work (and was a regression from my previous code). We always do duplicate allocations for headers, even if they already match the canonical format.

I think we should check first if they match the canonical format, in which case the duplicate allocations should be skipped. Right now we always check and always allocate.
