Examples of org.apache.http.client.cache.HttpCacheEntry

org.apache.http.client.cache.HttpCacheEntry
Structure used to store an {@link HttpResponse} in a cache. Some entriescan optionally depend on system resources that may require explicit deallocation. In such a case {@link #getResource()} should return a nonnull instance of {@link Resource} that must be deallocated by calling{@link Resource#dispose()} method when no longer used. @since 4.1
