Package filters contains all the http handler chain filters which are not api related.
func BasicLongRunningRequestCheck(longRunningVerbs, longRunningSubresources sets.String) apirequest.LongRunningRequestCheck
BasicLongRunningRequestCheck returns true if the given request has one of the specified verbs or one of the specified subresources, or is a profiler request.
WithCORS is a simple CORS implementation that wraps an http Handler. Pass nil for allowedMethods and allowedHeaders to use the defaults. If allowedOriginPatterns is empty or nil, no CORS support is installed.
WithContentType sets both the Content-Type and the X-Content-Type-Options (nosniff) header
func WithMaxInFlightLimit( handler http.Handler, nonMutatingLimit int, mutatingLimit int, longRunningRequestCheck apirequest.LongRunningRequestCheck, ) http.Handler
WithMaxInFlightLimit limits the number of in-flight requests to buffer size of the passed in channel.
WithPanicRecovery wraps an http Handler to recover and log panics (except in the special case of http.ErrAbortHandler panics, which suppress logging).
func WithPriorityAndFairness( handler http.Handler, longRunningRequestCheck apirequest.LongRunningRequestCheck, fcIfc utilflowcontrol.Interface, ) http.Handler
WithPriorityAndFairness limits the number of in-flight requests in a fine-grained way.
WithProbabilisticGoaway returns an http.Handler that send GOAWAY probabilistically according to the given chance for HTTP2 requests. After client receive GOAWAY, the in-flight long-running requests will not be influenced, and the new requests will use a new TCP connection to re-balancing to another server behind the load balance.
WithTimeout returns an http.Handler that runs h with a timeout determined by timeoutFunc. The new http.Handler calls h.ServeHTTP to handle each request, but if a call runs for longer than its time limit, the handler responds with a 504 Gateway Timeout error and the message provided. (If msg is empty, a suitable default message will be sent.) After the handler times out, writes by h to its http.ResponseWriter will return http.ErrHandlerTimeout. If timeoutFunc returns a nil timeout channel, no timeout will be enforced. recordFn is a function that will be invoked whenever a timeout happens.
func WithTimeoutForNonLongRunningRequests(handler http.Handler, longRunning apirequest.LongRunningRequestCheck, timeout time.Duration) http.Handler
WithTimeoutForNonLongRunningRequests times out non-long-running requests after the time given by timeout.
func WithWaitGroup(handler http.Handler, longRunning apirequest.LongRunningRequestCheck, wg *utilwaitgroup.SafeWaitGroup) http.Handler
WithWaitGroup adds all non long-running requests to wait group, which is used for graceful shutdown.

GetClassification returns the classification associated with the given context, if any, otherwise nil
