isCacheable()

isCacheable() : boolean

Returns true if the response may safely be kept in a shared (surrogate) cache.

Responses marked "private" with an explicit Cache-Control directive are considered uncacheable.

Responses with neither a freshness lifetime (Expires, max-age) nor cache validator (Last-Modified, ETag) are considered uncacheable because there is no way to tell when or how to remove them from the cache.

Note that RFC 7231 and RFC 7234 possibly allow for a more permissive implementation, for example "status codes that are defined as cacheable by default [...] can be reused by a cache with heuristic expiration unless otherwise indicated" (https://tools.ietf.org/html/rfc7231#section-6.1)

Returns

boolean —

true if the response is worth caching, false otherwise

isFresh()

isFresh() : boolean

Returns true if the response is "fresh".

Fresh responses may be served from cache without any interaction with the origin. A response is considered fresh when it includes a Cache-Control/max-age indicator or Expires header and the calculated age is less than the freshness lifetime.

Returns

boolean —

true if the response is fresh, false otherwise

isValidateable()

isValidateable() : boolean

Returns true if the response includes headers that can be used to validate the response with the origin server using a conditional GET request.

Returns

boolean —

true if the response is validateable, false otherwise

setPrivate()

setPrivate() : $this

Marks the response as "private".

It makes the response ineligible for serving other clients.

Returns

$this

setPublic()

setPublic() : $this

Marks the response as "public".

It makes the response eligible for serving other clients.

Returns

$this

setImmutable()

setImmutable(boolean  $immutable = true) : $this

Marks the response as "immutable".

Parameters

boolean $immutable

enables or disables the immutable directive

Returns

$this

isImmutable()

isImmutable() : boolean

Returns true if the response is marked as "immutable".

Returns

boolean —

returns true if the response is marked as "immutable"; otherwise false

mustRevalidate()

mustRevalidate() : boolean

Returns true if the response must be revalidated by caches.

This method indicates that the response must not be served stale by a cache in any circumstance without first revalidating with the origin. When present, the TTL of the response should not be overridden to be greater than the value provided by the origin.

Returns

boolean —

true if the response must be revalidated by a cache, false otherwise

getDate()

getDate() : \DateTime

Returns the Date header as a DateTime instance.

Throws

\RuntimeException

When the header is not parseable

Returns the age of the response.

Returns

integer —

The age of the response in seconds

expire() : $this

Marks the response stale by setting the Age header to be equal to the maximum age of the response.

Returns

$this

getExpires()

getExpires() : \DateTime|null

Returns the value of the Expires header as a DateTime instance.

Returns

\DateTime|null —

A DateTime instance or null if the header does not exist

setExpires()

setExpires(\DateTime|null  $date = null) : $this

Sets the Expires HTTP header with a DateTime instance.

Passing null as value will remove the header.

Parameters

\DateTime|null $date

A \DateTime instance or null to remove the header

Returns

$this

getMaxAge()

getMaxAge() : integer|null

Returns the number of seconds after the time specified in the response's Date header when the response should no longer be considered fresh.

First, it checks for a s-maxage directive, then a max-age directive, and then it falls back on an expires header. It returns null when no maximum age can be established.

Returns

integer|null —

Number of seconds

setMaxAge()

setMaxAge(integer  $value) : $this

Sets the number of seconds after which the response should no longer be considered fresh.

This methods sets the Cache-Control max-age directive.

Parameters

integer $value

Number of seconds

Returns

$this

Parameters

integer $value

Number of seconds

Returns

$this

getTtl()

getTtl() : integer|null

Returns the response's time-to-live in seconds.

It returns null when no freshness information is present in the response.
