| * from RFC2616: |
| * CTL = <any US-ASCII control character (octets 0 - 31) and DEL (127)> |
| * SEP = one of the 17 defined separators or SP or HT |
| * LWS = CR, LF, SP or HT |
| * SPHT = SP or HT. Use this macro and not a boolean expression for best speed. |
| * CRLF = CR or LF. Use this macro and not a boolean expression for best speed. |
| * token = any CHAR except CTL or SEP. Use this macro and not a boolean expression for best speed. |
| * |
| * added for ease of use: |
| * ver_token = 'H', 'P', 'T', '/', '.', and digits. |
