Disclosed are systems and methods for application streaming over HTTP. A virtual application running on a host computing device may detect the need for a page of memory that is not present on the host computing device. Accordingly, the virtual application may send a request to a virtual application server, seeking the absent memory page. The virtual application server may send to a web server an HTTP GET byte range request for the desired memory page. The web server may retrieve the requested block, which may be a portion of the virtual application image file. The requested data is returned to the host computing device via the virtual application server. The virtual application continues running on the host device using the requested data.
