get

public CacheResponse get(URI uri,
                         String rqstMethod,
                         Map<String,List<String>> rqstHeaders)
                  throws IOException

Description copied from class: java.net.ResponseCache

Retrieve the cached response based on the requesting uri, request method and request headers. Typically this method is called by the protocol handler before it sends out the request to get the network resource. If a cached response is returned, that resource is used instead.

Specified by:

get in class ResponseCache

Parameters:

uri - a URI used to reference the requested network resource

rqstMethod - a String representing the request method

rqstHeaders - - a Map from request header field names to lists of field values representing the current request headers

Returns:

a CacheResponse instance if available from cache, or null otherwise

Throws:

IOException - if an I/O error occurs

put

public CacheRequest put(URI uri,
                        URLConnection conn)
                 throws IOException

Description copied from class: java.net.ResponseCache

The protocol handler calls this method after a resource has been retrieved, and the ResponseCache must decide whether or not to store the resource in its cache. If the resource is to be cached, then put() must return a CacheRequest object which contains a WriteableByteChannel that the protocol handler will use to write the resource into the cache. If the resource is not to be cached, then put must return null.

Specified by:

put in class ResponseCache

Parameters:

uri - a URI used to reference the requested network resource

conn - - a URLConnection instance that is used to fetch the response to be cached

Returns:

a CacheRequest for recording the response to be cached. Null return indicates that the caller does not intend to cache the response.

Throws:

IOException - if an I/O error occurs
