44 | /* | |
2ac76861 | 45 | * On naming conventions: |
46 | * | |
47 | * HTTP/1.1 defines message-header as | |
48 | * | |
49 | * message-header = field-name ":" [ field-value ] CRLF | |
50 | * field-name = token | |
51 | * field-value = *( field-content | LWS ) | |
52 | * | |
53 | * HTTP/1.1 does not give a name name a group of all message-headers in a message. | |
54 | * Squid 1.1 seems to refer to that group _plus_ start-line as "headers". | |
55 | * | |
56 | * HttpHeader is an object that represents all message-headers in a message. | |
57 | * HttpHeader does not manage start-line. | |
58 | * | |
d8b249ef | 59 | * HttpHeader is implemented as a collection of header "entries". |
60 | * An entry is a (field_id, field_name, field_value) triplet. | |
