2ac76861 | 54 | * On naming conventions: |

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