Step S2: the main source station returns a 302 status code to the CDN node, the CDN node automatically jumps to access a 302 address in the 302 source station responded by the 302 status code, stores the 302 address, establishes and maintains a long link with the 302 source station, and normally, when the CDN node initiates an HTTP access request to the 302 source station, the CDN node firstly establishes a TCP link with the 302 source station, then carries out HTTP protocol communication with the 302 source station through the link, and actively releases the TCP link after the end, so that the TCP link needs to be re-established for the next HTTP access request, however, the long link is a TCP link between the CDN node and the 302 source station, the TCP link keeps the TCP link between the CDN node and the 302 source station continuous, and the establishment time of each request is saved, so that the aim of quick access is achieved; the 302 state code is a state code commonly used in http standard protocols, and the master source station informs the user terminal to access a new Uniform Resource Identifier (URI) to acquire resources by adding a Location parameter in an http response header, and normally, the master source station performs scheduling and load balancing control through the 302 state code to prevent the situation of overhigh single-point load, and referring to fig. 1 specifically, for example, the process includes: 1) The network user accesses the source station a.com through the user terminal;
2) The source station a.com returns 302 a status code to the user terminal according to http:// a.com/1.Txt, wherein the Location parameter is: the new uniform resource identifier is http:// b.com/1.Txt;
3) The network user accesses the source station b.com through the user terminal;
4) The source station b.com returns the corresponding resource content to the user terminal according to http:// b.com/1. Txt.
Specifically, when the 302 status code returned by the main source station is accessed through the CDN node, the CDN node may automatically jump to access the 302 address to which the 302 status code corresponds, and obtain the resource content to return to the user terminal, thereby saving access time of the user terminal, and referring specifically to fig. 2, for example, the process includes:
1) The network user accesses CDN nodes through a user terminal;
2) The CDN node accesses http:// a.com/1.Txt at the master source station;
3) The primary source station returns 302 a status code to the CDN node, wherein the Location parameter is: the new uniform resource identifier is http:// b.com/1.Txt;
4) The CDN node directly accesses http:// b.com/1.Txt at the 302 source station following the 302 state code;
5) 302, the source station returns the corresponding resource content to the CDN node;
6) And the CDN node returns the corresponding resource content to the user terminal, and at the same time, the CDN node caches the corresponding resource content.
Step S3: and the 302 source station returns the resource content corresponding to the first slicing request to the CDN node, and the CDN node returns the resource content corresponding to the first slicing request to the user terminal, and at the same time, the CDN node caches the resource content corresponding to the first slicing request.
Step S4: the CDN node directly uses the stored 302 address, and sends the resource content corresponding to the second slicing request through the maintained long-link request 302 source station.
Step S5: and the 302 source station returns the resource content corresponding to the second slicing request to the CDN node, and the CDN node returns the resource content corresponding to the second slicing request to the user terminal, and at the same time, the CDN node caches the resource content corresponding to the second slicing request.
Step S6: the CDN node directly uses the stored 302 address, and sends the resource content corresponding to the third slicing request through the maintained long-chain request 302 source station, and so on, the CDN node repeatedly uses the stored 302 address, and sends the resource content corresponding to the rest of slicing requests through the maintained long-chain request 302 source station until the resource content corresponding to the rest of slicing requests in the N slicing requests is obtained, wherein N is the total number of the plurality of slicing requests which are sequentially arranged.
As shown in fig. 3, in one embodiment of the present application, the method for improving the downloading speed of a fragmentation request based on a multiplexing 302 address provided by the present application includes the following steps:
step S101: the network user initiates a resource access request of 0-2M resource content to a CDN node through a user terminal, the CDN node splits the resource access request of the 0-2M resource content into a slicing request of 0-1M resource content and a slicing request of 1-2M resource content, and sends the slicing request of the 0-1M resource content to a main source station for source returning operation;
step S102: the main source station returns a 302 state code to the CDN node, and the CDN node automatically jumps to access a 302 address in the 302 source station responded by the 302 state code, saves the 302 address, and establishes and maintains a long link with the 302 source station;
