EasyURLDownloader is a fast and easy way to download files in the iPhone Cocoa framework. Also, you may optionally use the included EasyCache cache object as a replacement to the NSURLCache object that is used by default in the Cocoa framework. When using EasyCache, EasyURLDownloader will automatically take advantage of HTTP Conditional Gets (If-Modified-Since, If-None-Match) to only fetch objects that do not exist in the cache. Additionally, EasyURLDownloader will automatically flush cached objects to disk when the in-memory limit of objects is exceeded; the amount of disk and memory capacity may be configured by EasyCache's setMemoryCapacity: and setDiskCapacity: methods.. You may force a flush to disk at any time.
