The type of encoding used on the data.

Int? contentLength

The length of the response body in octets (8-bit bytes).

Example: Content-Length: 348

contentType

Source

MimeType? contentType

The MIME type of this content.

Example: Content-Type: text/html; charset=utf-8

eTag

expires

Source

DateTime? expires

Gives the date/time after which the response is considered stale.

location

Source

Uri? location

Used in redirection, or when a new resource has been created.

Example: Location: http://www.w3.org/pub/WWW/People.html

map

Source

Str:Str map()

Returns a read / write map of the response headers.

It is better to use set() / remove() / or one of the setters on this HttpResponseHeaders instance to change response values. This allows us to check if the response has already been committed before updating header values.

Think of this map as a get-out-jail card.

pragma

Source

Str? pragma

Implementation-specific headers.

Example: Pragma: no-cache

remove

Source

Str? remove(Str name)

Removes a response header.

set

Source

@Operator Void set(Str name, Str? value)

Sets a response head to the given value.

If the given value is null then it is removed.

vary

Source

Str? vary

Tells downstream proxies how to match future request headers to decide whether the cached response can be used rather than requesting a fresh one from the origin server.

Example: Vary: Accept-Encoding

@see Accept-Encoding, It’s Vary important
