Normalization for parameters

[martinthomson]

Are the following header fields considered equal or equivalent or are they different?

Header: value; p=pval
Header: value; p="pval"
Header: value; p="Pval"
Header: value; P="Pval"

Some specializations of the header syntax permit both quoted-string and token for parameter values. If the string value after removal of quotes is the same as the token, is it the same value?

What about case folding for parameter names? Do we do that?

[reschke]

1. and 2) should be the same (token vs quoted string)

2. is different

3. might be the same as 3), there are at least some pre-existing header fields that treat parameter names case-insensitively.

[martinthomson]

That was my guess too, but the more pertinent question is: where is that written down?

[reschke]

We need to write it down.

I can see a point of automatically "promoting" an ascii-string to identifier if removing the quotes would make it one.

For the remaining questions I think the individual header definition should sort that out.

I think this is OBE - @martinthomson can we close?

[martinthomson]

I think that the question remains relevant, but are you suggesting that I make it a 723x-bis question instead?

[mnot]

Well, if you want it to be addressed for token and quoted-string in parameter, it needs to be raised against httpter, yes. If you want it to be addressed within structured headers, I think it is OBE.

[martinthomson]

I'll reopen on bisbisbis then.
