Abstract

Embodiments enable HTTP servers to pass incomplete and/or corrupted files in response to file requests from clients. In the various embodiments, HTTP servers may be enabled to generate status codes identifying that an incomplete version of a file is being returned in response to a file request. In an embodiment, an HTTP server may be enabled to determine the ability of a client to handle incomplete versions of files.

Claims (106)

1. A method for delivering an incomplete response from a Hypertext Transfer Protocol (HTTP) server to a client, comprising:

receiving a file request in the HTTP server from the client for a file or a byte range of the file at the HTTP server, wherein the file request indicates whether the client is capable of using an incomplete response;

determining in the HTTP server, based on the file request, whether the client is capable of using an incomplete response; and

sending from the HTTP server to the client an incomplete response in response to determining that the client is capable of using an incomplete response if a full response including an entirety of the file or the byte range of the file is not available at the HTTP server and the file or the byte range of the file requested by the file request is partially available at the HTTP server;
