Examples of ResponseCache

ch.entwine.weblounge.common.request.ResponseCache
The ResponseCache is used to cache responses generated using the WebloungeResponse object. It's implementation makes sure that the response that is handed over in the first place is tweaked (wrapped) in a way that the output that is written to it is streamed to the cache as well as to the client.
The structure of the response cache is hierarchical in that there is a general response, consisting of stacked response parts. This supports content structures that have different lifetimes, e. g. a page might become invalid but some pieces on it live much longer. When a client requests that invalidated page, the output renderer needs to produce the enclosing content (template) from scratch but could choose to reuse the cached pieces.
The two methods {@link #startResponse(CacheTag[],WebloungeRequest,WebloungeResponse,long,long)}and {@link #startResponsePart(CacheTag[],HttpServletResponse,long,long)}are used to create an entry in the cache. They will return null if the entry is already present, meaning that the cached version will be sent to the client. If a CacheHandle is returned, then a new cache entry, identified by the handle, was created and the output written to the response will be sent to both the cache and the client.
Note that in order to take advantage of the cache, it is crucial that you tag your responses and their parts in a useful manner.
io.undertow.server.handlers.cache.ResponseCache
Facade for an underlying buffer cache that contains response information.
This facade is attached to the exchange and provides a mechanism for handlers to serve cached content. By default a request to serve cached content is interpreted to mean that the resulting response is cacheable, and so by default this will result in the current response being cached (as long as it meets the criteria for caching).
Calling tryServeResponse can also result in the exchange being ended with a not modified response code, if the response headers indicate that this is justified (e.g. if the If-Modified-Since or If-None-Match headers indicate that the client has a cached copy of the response)
This should be installed early in the handler chain, before any content encoding handlers. This allows it to cache compressed copies of the response, which can significantly reduce CPU load.
NOTE: This cache has no concept of authentication, it assumes that if the underlying handler indicates that a response is cachable, then the current user has been properly authenticated to access that resource, and that the resource will not change per user. @author Stuart Douglas
