Metadata keys (the name of the metadata) must be treated as case-insensitive
|
||
|
at all times. These keys can contain ASCII 7-bit characters that are not
|
||
|
control (0-31) characters, DEL, or a separator character, according to
|
||
|
`HTTP/1.1 <http://www.w3.org/Protocols/rfc2616/rfc2616.html>`_ .

|
The underscore character is silently converted to a hyphen.
