  * See https://tools.ietf.org/html/rfc7230#section-3.2.6

- * Allowed characters in an HTTP token:
- * ^_`a-z  94-122
- * A-Z     65-90

- * 0-9     48-57

- * This implementation of checkIsHttpToken() loops over the string instead of
- * using a regular expression since the former is up to 180% faster with v8 4.9
- * depending on the string length (the shorter the string, the larger the
- * performance difference)
- *
- * Additionally, checkIsHttpToken() is currently designed to be inlinable by v8,
- * so take care when making changes to the implementation so that the source
- * code size does not exceed v8's default max_inlined_source_size setting.
