31 * some macros used for the request parsing.
32 * from RFC2616:
33 * CTL = <any US-ASCII control character (octets 0 - 31) and DEL (127)>
Willy Tarreau8d5d7f22007-01-21 19:16:41 +010034 * SEP = one of the 17 defined separators or SP or HT
35 * LWS = CR, LF, SP or HT
36 * SPHT = SP or HT. Use this macro and not a boolean expression for best speed.
37 * CRLF = CR or LF. Use this macro and not a boolean expression for best speed.
38 * token = any CHAR except CTL or SEP. Use this macro and not a boolean expression for best speed.
Willy Tarreau4b89ad42007-03-04 18:13:58 +010039 *
40 * added for ease of use:
41 * ver_token = 'H', 'P', 'T', '/', '.', and digits.
