Abstract: Disclosed are a hypertext transfer protocol (HTTP) request transmission method and device. The HTTP request transmission method and device resolve a problem that data finally obtained through splicing is invalid because dividing an original HTTP request into a plurality of HTTP requests to pull data from different content distribution network (CDN) servers may cause inconsistency of the pulled data. When an electronic device needs to download data from a plurality of CDN servers, an overlapping range may be designed for byte ranges allocated to the different CDN servers. This means that the electronic device downloads data in the overlapping range from all the different CDN servers. Therefore, this part of data is used to check consistency of the data pulled from the different CDN servers. When determining that the data pulled from the different CDN servers is consistent, the electronic device may splice the data to obtain finally required data.

Abstract: This application provides a method for multiplexing HTTP channels. The method includes: sending, by the terminal, a first HTTP request to a first server through a first HTTP channel, to request first data; after receiving a first HTTP response returned by the first server, receiving, through the first HTTP channel, a first part that is of the first data and that is sent by the first server; and if a size that is of the first data and that is carried in the first HTTP response is greater than a first threshold, generating a second HTTP request, and sending a second HTTP request to a second server through a second HTTP channel, to request a second part of the first data; and after receiving the first part of the first data, sending control signaling to the first server, to disconnect the first HTTP channel.

Abstract: A multipath aggregation scheduling method and an electronic device provide for configuring transmission sequences of network packets on different paths when there are a plurality of paths between a client and a service end. This enables a network packet sent later on any of the plurality of paths to be sent first on at least one other path, thereby increasing transmission rate of the network.

Abstract: A method may be applied to an electronic device configured with a foldable display. The display includes a first area, a second area, and a third area, and when the electronic device is in a folded form, an included angle between the first area and the third area is less than a first preset angle, and two sides of a third area are the first area and the second area. The method includes: displaying a first interface in the first area, where the first interface includes one or more touchable areas; determining a first touch area between a user and the third area; mapping a touch function of a first touchable area in the first interface to the first touch area; detecting a first operation in the first touch area; and controlling the first touchable area in the first interface based on the first operation.

Abstract: A connection establishment method includes a terminal device obtaining historical data of a multipath transmission control protocol (MPTCP) connection established between the terminal device and an application server. The historical data includes a data transmission delay of a transmission control protocol (TCP) connection corresponding to a Wi-Fi network and a data transmission delay of a TCP connection corresponding to a cellular network. The terminal device determines, based on the historical data, that the data transmission delay of the TCP connection corresponding to the cellular network is less than or equal to the data transmission delay of the TCP connection corresponding to the Wi-Fi network, and establishes a first TCP connection to the application server through an interface of the cellular network; and after the first TCP connection is successfully established, the terminal device establishes a second TCP connection to the application server through an interface of the Wi-Fi network.
