HTTP request transmission method and device

An electronic device, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and configured to store programming instructions that, when executed by the at least one processor, cause the electronic device to perform operations comprising:
• allocating, based on a byte range of to-be-requested data, a first byte range to a first content distribution network (CDN) server and allocating a second byte range to a second CDN server, wherein there is an overlapping range between the first byte range and the second byte range, wherein the allocating the first byte range to the first CDN server and the second byte range to the second CDN server comprises:
• allocating, based on the byte range of the to-be-requested data, a third byte range to the first CDN server and a fourth byte range to the second CDN server, wherein there is no overlapping range between the third byte range and the fourth byte range;
• and
• adjusting, based on a predefined initial value, an end byte of requested data identified by the third byte range, to obtain the first byte range, and using the fourth byte range as the second byte range;
• sending a first HTTP request to the first CDN server based on the first byte range;
• and
• sending a second HTTP request to the second CDN server based on the second byte range,
• wherein the first HTTP request is at least used to download first data from the first CDN server, the second HTTP request is at least used to download second data from the second CDN server, and the first data and the second data each are data whose byte range is the overlapping range and are used to check consistency between data downloaded from the first CDN server and data downloaded from the second CDN server.
