// OpenBSD, Windows, and illumos do not support O_DIRECT.
// On Windows there is no documentation on disabling O_DIRECT.
// For these systems we do not attempt to build the 'directio' dependency since
// the O_DIRECT symbol may not be exposed resulting in a failed build.

// On illumos an explicit O_DIRECT flag is not necessary for two primary
// reasons. Note that ZFS is effectively the default filesystem on illumos

`Header` hat weitere Funktionalität, zusätzlich zu der, die `Path`, `Query` und `Cookie` bereitstellen.

Die meisten Standard-Header benutzen als Trennzeichen einen Bindestrich, auch bekannt als das „Minus-Symbol“ (`-`).

Aber eine Variable wie `user-agent` ist in Python nicht gültig.

Darum wird `Header` standardmäßig in Parameternamen den Unterstrich (`_`) zu einem Bindestrich (`-`) konvertieren.

                            isSpace = removeLastDuplication(buf, alphanumSize, isSpace, termCache);
                        }
                        // symbol
                        if (maxSymbolTermSize >= 0) {
                            if (symbolSize < maxSymbolTermSize) {
                                buf.appendCodePoint(c);
                                symbolSize++;

## Automatic conversion

`Header` has a little extra functionality on top of what `Path`, `Query` and `Cookie` provide.

Most of the standard headers are separated by a "hyphen" character, also known as the "minus symbol" (`-`).

But a variable like `user-agent` is invalid in Python.

So, by default, `Header` will convert the parameter names characters from underscore (`_`) to hyphen (`-`) to extract and document the headers.
