One method includes an operation for initializing, at a client device, a hypertext transfer protocol (HTTP) server for processing streaming video requests from a streaming video application. Further; the method includes an operation for receiving a bundle that includes bundle files, which include manifest files of a manifest for streaming a video and video files having video data. The method further includes operations for caching the bundle files in memory, and for intercepting, at the HTTP server, a request for a file from the streaming video application. When the file is cached in the memory, the file is returned from the memory; otherwise, the HTTP server acts as a proxy by forwarding the request to a video server and then returning the file to the streaming video application after the file is received from the remote server. ## Claims ### Claim 1 A method comprising: identifying, by a processor, a first user account of a first user in a social network; determining a video to be preloaded based on the first user account; creating a bundle for the video including bundle files, the bundles files including manifest files of a manifest for streaming the video and one or more video files having video data for corresponding segments of the video; transmitting the bundle to a client device associated with the first user account, wherein the bundle files are cached in the client device; and causing the client device to erase the bundle files after a predetermined amount of time has elapsed without any of the bundle files being requested. ### Claim 2 (depends on 1) The method of claim 1, wherein determining the video to be preloaded comprises determining a probability of the first user requesting presentation of the video. ### Claim 3 (depends on 1) The method of claim 1, wherein determining the video to be preloaded comprises determining a probability of the first user requesting presentation of the video based on actions of a second user associated with the first user in the social network. ### Claim 4 (depends on 1) The method of claim 1, wherein the one or more video files comprise: a first video file with video data for an initial video segment of the video; and a second video file with video data for a video segment that immediately follows the initial video segment of the video. ### Claim 5 (depends on 1) The method of claim 1, wherein the one or more video files include video data for a low-resolution rendition of the video, wherein the one or more video files are indexed in a low-resolution index file in the manifest files. ### Claim 6 (depends on 1) The method of claim 1, wherein the manifest files comprise a bundle index file, a low-resolution index file, a medium-resolution index file, and a high-resolution index file. ### Claim 7 (depends on 1) The method of claim 1, further comprising: caching, by the client device, the bundle files in a memory included in the client device; intercepting, by an HTTP server in the client device, a request from a streaming video application, the request including an identification of a requested file; when the requested file is a file included in the bundle files cached in the memory, transmitting the file included in the bundle files from the memory to the streaming video application; and when the requested file is absent from the memory, forwarding the request by the HTTP server to a video server and transmitting by the HTTP server the requested file to the streaming video application after the requested file is received from the video server. ### Claim 8 A non-transitory computer-readable storage medium, having stored thereon instructions, when executed by a processor, causes the processor to perform operations comprising: identifying a first user account of a first user in a social network; determining a video to be preloaded based on the first user account; creating a bundle for the video including bundle files, the bundle files including manifest files of a manifest for streaming the video and one or more video files having video data for corresponding segments of the video; transmitting the bundle to a client device associated with the first user account wherein the bundle files are cached in the client device; and causing the client device to erase the bundle files after a predetermined amount of time has elapsed without any of the bundle files being requested. ### Claim 9 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein determining the video to be preloaded comprises determining a probability of the first user requesting presentation of the video. ### Claim 10 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein determining the video to be preloaded comprises determining a probability of the first user requesting presentation of the video based on actions of a second user associated with the first user in the social network. ### Claim 11 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein the one or more video files comprise: a first video file with video data for an initial video segment of the video; and a second video file with video data for a video segment that immediately follows the initial video segment of the video. ### Claim 12 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein the one or more video files include video data for a low-resolution rendition of the video, wherein the one or more video files are indexed in a low-resolution index file in the manifest files. ### Claim 13 (depends on 8) The non-transitory computer-readable storage medium of claim 8, wherein the manifest files comprise a bundle index file, a low-resolution index file, a medium-resolution index file, and a high-resolution index file. ### Claim 14 A system comprising: a processor; and a memory having instructions stored thereon, when executed by the processor, causes the system to perform operations comprising: identifying a first user account of a first user in a social network; determining a video to be preloaded based on the first user account; creating a bundle for the video including bundle files, the bundle files including manifest files of a manifest for streaming the video and one or more video files having video data for corresponding segments of the video; transmitting the bundle to a client device associated with the first user account, wherein the bundle files are cached in the client device; and causing the client device to erase the bundle files after a predetermined amount of time has elapsed without any of the bundle files being requested. ### Claim 15 (depends on 14) The system of claim 14, wherein determining the video to be preloaded comprises determining a probability of the first user requesting presentation of the video. ### Claim 16 (depends on 1) The method of claim 1, wherein determining the video to be preloaded comprises determining a probability of the first user requesting presentation of the video based on actions of a second user associated with the first user in the social network. ### Claim 17 (depends on 14) The system of claim 14, wherein the one or more video files comprise: a first video file with video data for an initial video segment of the video; and a second video file with video data for a video segment that immediately follows the initial video segment of the video. ### Claim 18 (depends on 14) The system of claim 14, wherein the one or more video files include video data for a low-resolution rendition of the video. ### Claim 19 (depends on 18) The system of claim 18, wherein the one or more video files are indexed in a low-resolution index file in the manifest files. ### Claim 20 (depends on 14) The system of claim 14, wherein the manifest files comprise a bundle index file, a low-resolution index file, a medium-resolution index file, and a high-resolution index file.
