1. A computer-implemented method performed by a server computing device connected to a requesting computing device, the method comprising: receiving a request from the requesting computing device to download an application file via a conventional download protocol without using a specialized streaming protocol, when executing, the application file implementing an application; in response to the request, downloading a streaming model file and one or more initial execution files to the requesting computing device via the conventional download protocol without using a specialized streaming protocol, the one or more initial execution files comprising a first portion of the application file that is less than the entire application file but contains enough data to initiate execution of the application on the requesting computing device, the streaming model file comprising download information; and as the application is executing on the requesting computing device and until the entire application file has been downloaded to the requesting computing device, receiving requests from the requesting computing device to download one or more other files each comprising another portion of the application file in accordance with the download information of the streaming model file, and in response to the requests to download the one or more other files, downloading the one or more other files to the requesting computing device via the conventional download protocol without using a specialized streaming protocol, wherein the requests to download the one or more other files comprise (i) a request to download one or more sequence files each comprising a portion of the application file not contained in the first portion of the application file, and (ii) a request to download one or more rest files each comprising portions of the application file ordered by frequency in which the portions of the application file were accessed during a profiling process performed when the application was executed previously.
