2ac76861 | 50 | * On naming conventions: |
26ac0430 AJ |
51 | * |
52 | * HTTP/1.1 defines message-header as | |
53 | * | |
2ac76861 | 54 | * message-header = field-name ":" [ field-value ] CRLF |
55 | * field-name = token | |
56 | * field-value = *( field-content | LWS ) | |
26ac0430 | 57 | * |
2ac76861 | 58 | * HTTP/1.1 does not give a name name a group of all message-headers in a message. |
59 | * Squid 1.1 seems to refer to that group _plus_ start-line as "headers". | |
26ac0430 | 60 | * |
2ac76861 | 61 | * HttpHeader is an object that represents all message-headers in a message. |
62 | * HttpHeader does not manage start-line. | |
26ac0430 | 63 | * |
d8b249ef | 64 | * HttpHeader is implemented as a collection of header "entries". |
65 | * An entry is a (field_id, field_name, field_value) triplet. | |
