Provided are arrangements for downloading resources and managing downloaded resources. A file is requested from a HTTP server, the file associated with an original URI. The file is downloaded and assigned a handle. The file is then stored in a storage location such as a file cache or in a persistent storage location. Upon command of an advanced content playlist or sequence, the file is called by calling the handle of the file. The storing of the file may include storing the file in a location where the file is subject to an automatic removal operation. The file may be an image file or any other type of file, especially multimedia files. The automatic removal operation may occur upon a quitting or restarting of the application. If another request is made for another file, the prior downloaded file may be replaced.
