[0024] After the Cache server receives the redirect response from the source site, it sends the redirect response to the client, and then the client sends the content acquisition request to the Cache server again. The client needs to establish connections with the network side multiple times, making the whole process time Longer and more complicated process

Embodiment 1

[0053] Such as image 3 Shown:

[0054] Step 1: The browser of the client sends a content acquisition request including the URL address A, and the content acquisition request is located on the Cache server.

[0055] Step 2: When the Cache server does not cache the content data requested by the content acquisition request, it sends the content acquisition request to the origin site A according to the address in the content acquisition request.

[0056] Step 3: When the source site A does not save the content data requested by the content acquisition request, it returns a jump response to the cache server. The jump response carries the address that needs to be requested in the next step, that is, the jump address pointing to the source site B : URL address B, the content data may be saved in the origin site B;

[0057] Step 4: The Cache server sends a content acquisition request to the origin site B according to the redirection address in the redirection response;

Embodiment 2

[0062] Step 1: The browser of the client sends a content acquisition request including the URL address A, and the content acquisition request is located on the Cache server.

[0063] Step 2: When the Cache server does not cache the content data requested by the content acquisition request, it sends the content acquisition request to the origin site A according to the address in the content acquisition request.

[0064] Step 3: The origin site A returns a redirect response to the cache server, the redirect response carries a file content list, which contains multiple fragment URL addresses corresponding to the requested content data, and each fragment URL address points to a saved The source site of the requested part of the content data;

[0065] Step 4: The Cache server uses the segment URL address in the file content list as the jump address, and sends a content acquisition request to the source site pointed to by each jump address;

[0066] Step 5: The source site that rec...

Abstract

The embodiment of the invention discloses a method and a device for processing a jump response in a CDN (Content Delivery Network), relates to the Internet and CDN field, and is used for simplifying the complexity of the jump processing in the CDN. According to the invention, the method comprises the following steps: a cache server sends a request to a first source station for obtaining content; if the cache server receives the jump response with a jump address returned by the first source station, a request is sent to a second source station for obtaining the content according to the jump address; and if the cache server receives a non jump response with the content data requested by the content obtaining request returned by the first source station, the content data is sent to a client side. The invention can simplify the complexity in processing the jump response in the CDN, improve the jump request processing efficiency in the CDN, and is more intelligent.

Description

technical field [0001] The present invention relates to the field of the Internet and content distribution networks, in particular to a jump response processing method and equipment in the content distribution network. Background technique [0002] In the content delivery network (Content Delivery Network, CDN), by directing the user's access to the cache server, the user can obtain the required content nearby, avoiding the need to go back to the source site to obtain the content through various routes , so as to achieve the effect of access acceleration. [0003] Various acceleration protocols provided by CDN, including hypertext transfer protocol (HTTP), file transfer protocol (FTP), point-to-point (P2P) protocol, etc. For example, the 301 redirection rule and the 302 redirection rule are defined in the HTTP protocol. When using these two redirection rules, the unified positioning resource (URL) address has been transferred, that is, the content that the user needs to obt...
