FORCE_NETWORK

public static final CacheControl FORCE_NETWORK

Cache control request directives that require network validation of responses. Note that such requests may be assisted by the cache via conditional GET requests.

FORCE_CACHE

public static final CacheControl FORCE_CACHE

Cache control request directives that uses the cache only, even if the cached response is stale. If the response isn't available in the cache or requires server validation, the call will fail with a 504 Unsatisfiable Request.

方法详细资料

parse

public static CacheControl parse(Headers headers)

Returns the cache directives of headers. This honors both Cache-Control and Pragma headers if they are present.

noCache

public boolean noCache()

In a response, this field's name "no-cache" is misleading. It doesn't prevent us from caching the response; it only means we have to validate the response with the origin server before returning it. We can do this with a conditional GET.

In a request, it means do not use a cache to satisfy the request.

noStore

public boolean noStore()

If true, this response should not be cached.

maxAgeSeconds

public int maxAgeSeconds()

The duration past the response's served date that it can be served without validation.

sMaxAgeSeconds

public int sMaxAgeSeconds()

The "s-maxage" directive is the max age for shared caches. Not to be confused with "max-age" for non-shared caches, As in Firefox and Chrome, this directive is not honored by this cache.

isPrivate

public boolean isPrivate()

isPublic

public boolean isPublic()

mustRevalidate

public boolean mustRevalidate()

maxStaleSeconds

public int maxStaleSeconds()

minFreshSeconds

public int minFreshSeconds()

onlyIfCached

public boolean onlyIfCached()

This field's name "only-if-cached" is misleading. It actually means "do not use the network". It is set by a client who only wants to make a request if it can be fully satisfied by the cache. Cached responses that would require validation (ie. conditional gets) are not permitted if this header is set.

noTransform

public boolean noTransform()

immutable

public boolean immutable()

toString

public String toString()
