2ac76861 | 55 | * On naming conventions: |
26ac0430 AJ |
56 | * |
57 | * HTTP/1.1 defines message-header as | |
58 | * | |
2ac76861 | 59 | * message-header = field-name ":" [ field-value ] CRLF |
60 | * field-name = token | |
61 | * field-value = *( field-content | LWS ) | |
26ac0430 | 62 | * |
2ac76861 | 63 | * HTTP/1.1 does not give a name name a group of all message-headers in a message. |
64 | * Squid 1.1 seems to refer to that group _plus_ start-line as "headers". | |
26ac0430 | 65 | * |
2ac76861 | 66 | * HttpHeader is an object that represents all message-headers in a message. |
67 | * HttpHeader does not manage start-line. | |
26ac0430 | 68 | * |
d8b249ef | 69 | * HttpHeader is implemented as a collection of header "entries". |
70 | * An entry is a (field_id, field_name, field_value) triplet. | |
