A method and device for feeding back a resource file

A device for feeding back a resource file, comprising:

• a first calculation module that is configured to receive a resource acquisition request of a target resource, and calculate resource identification information included in the resource acquisition request by using a first preset algorithm to obtain a target feature index value;
• a first transmission module that is configured to, if a resource file corresponding to the target feature index value exists locally, feed back the resource file corresponding to the target feature index value, and if the resource file corresponding to the target feature index value does not exist locally, transmit a data acquisition request of a specified segment of the target resource to a resource server of the target resource;
• a second calculation module that is configured to receive data of the specified segment of the target resource fed back by the resource server, and calculate the data of the specified segment by using a second preset algorithm to obtain a target content index value;
• and
• a second transmission module that is configured to, if a resource file corresponding to the target content index value exists locally, feed back the resource file corresponding to the target content index value, and if the resource file corresponding to the target content index value does not exist locally, transmit the resource acquisition request of the target resource to the resource server.

A cache server, comprising a processor and a memory, wherein the memory stores at least one instruction, at least one program, a code set, or an instruction set, that is loaded and executed by the processor to implement a method for feeding back a resource file, and the method includes:

• receiving a resource acquisition request of a target resource, and calculating resource identification information included in the resource acquisition request by using a first preset algorithm to obtain a target feature index value;
• if a resource file corresponding to the target feature index value exists locally, feeding back the resource file corresponding to the target feature index value, and if the resource file corresponding to the target feature index value does not exist locally, transmitting a data acquisition request of a specified segment of the target resource to a resource server of the target resource;
• receiving data of the specified segment of the target resource fed back by the resource server, and calculating the data of the specified segment by using a second preset algorithm to obtain a target content index value;
• and
• if a resource file corresponding to the target content index value exists locally, feeding back the resource file corresponding to the target content index value, and if the resource file corresponding to the target content index value does not exist locally, transmitting the resource acquisition request of the target resource to the resource server.
