etag()source public

If $code is an array, then the keys are used as codes and the values as messages to add to the default HTTP codes. The codes must be integers greater than 99 and less than 1000. Keep in mind that the HTTP specification outlines that status codes begin with a digit between 1 and 5, which defines the class of response the client is to expect. Example:

httpCodes(404); // returns [404 => 'Not Found']

   httpCodes([
       381 => 'Unicorn Moved',
       555 => 'Unexpected Minotaur'

Returns

Cake\Http\Response

withSharable()source public

withSharable( boolean $public , integer|null $time null )

Parameters

boolean $public

withSharedMaxAge()source public

withSharedMaxAge( integer $seconds )

Create a new instance with the Cache-Control s-maxage directive.

The max-age is the number of seconds after which the response should no longer be considered a good candidate to be fetched from a shared cache (like in a proxy server).

Parameters

integer $seconds

The number of seconds for shared max-age

Returns

Cake\Http\Response

withStatus()source public

withStatus( integer $code , string $reasonPhrase '' )

Return an instance with the specified status code and, optionally, reason phrase.

If no reason phrase is specified, implementations MAY choose to default to the RFC 7231 or IANA recommended reason phrase for the response's status code.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated status and reason phrase.

If the status code is 304 or 204, the existing Content-Type header will be cleared, as these response codes have no body.

Parameters

integer $code

The 3-digit integer result code to set.

string $reasonPhrase optional ''

The reason phrase to use with the provided status code; if none is provided, implementations MAY use the defaults as suggested in the HTTP specification.

Returns

Cake\Http\Response

Throws

InvalidArgumentException
For invalid status code arguments.

A single Vary string or an array containing the list for variances.
