mod_unzip is an Apache 2.0 module to transparently access files stored in ZIP archives. It is handy when multiple files that belong to the same context should be combined together without having to deal with a lot of files, such as HTML pages that contain images or articles that consist of multiple files. Access to files is very fast and the module does not create any temporary files nor does it load the whole archive into memory. It uses the external unzip program, which may cause a slight overhead due to a fork() operation for every file request from the ZIP archive.
