prepare()

prepare(\Symfony\Component\HttpFoundation\Request  $request) : $this

Returns

boolean —

true if the response is worth caching, false otherwise

It makes the response eligible for serving other clients.

Returns

$this

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

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

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.

Returns

integer|null —

The TTL in seconds

setTtl()
