Do NOT change the case of HTTP (header) tags values.

Hi,

IMO, the change of HTTP tags for comparison is fine but the values should remain intact.
For example, in case of custom headers the value may be a JSON object with strings in it.
I suggest that for all known headers it is okay to change the case (I can't think of a scenario where is should not) but for unknown headers it should NOT change the case.

Thanks!
