Redirect response is transmitted to client by step 4:Cache server.
Step 5: the browser of client continues to send the content acquisition request of carrying the jump address in redirect response, and this content acquisition request is positioned to Cache servers.
Step 6:Cache server sends content acquisition request to source station B.
Step 7: source station B returns to response to Cache servers, if this response is the non-redirect response of carrying the content-data of request to some extent, arrives step 8; If this response is to carry the redirect of another jump address response, carry out the method for similar step 4-step 7: redirect response is transmitted to client, the browser of client continues to send the content acquisition request of carrying the jump address in redirect response, this content acquisition request is positioned to Cache servers, and the source station (such as source station C) that Cache servers point to this jump address sends content acquisition request; Until receive the content-data that source station is returned.
Step 6:Cache server sends content acquisition request to source station B
The content-data in response is sent to client by step 8:Cache server.
Another kind of general situation is, file of client-requested, and what get for the first time is a file content list, the burst URL address that comprises this file in this file contents list, and then according to the real file of the content obtaining in file content list.Idiographic flow is as follows:
Step 1: the browser of client sends the request of obtaining to file, this request of obtaining is positioned on Cache servers.
Step 2:Cache server, in the time there is no this file of buffer memory, sends this content acquisition request to source station A.
Step 3: source station A, to the response of cache server return jump, carries file content list in this redirect response, wherein comprises multiple burst URL address of this file, and the source station of the partial data of preserving this file is pointed in each burst URL address, such as source station B;
Redirect response is transmitted to client by step 4:Cache server.
Step 5: the browser of client continues to send the content acquisition request of carrying URL address in file content list, and this content acquisition request is positioned to Cache servers.
Step 6:Cache server sends content acquisition request to source station B.
Step 7: source station B returns to response to Cache servers, if this response is the non-redirect response of carrying the file data of request to some extent, arrives step 8; If this response is to carry the redirect of other URL addresses response, carry out the method for similar step 4-step 7: redirect response is transmitted to client, the browser of client continues to send the content acquisition request of carrying the jump address in redirect response, this content acquisition request is positioned to Cache servers, and the source station (such as source station C) that Cache servers point to this jump address sends content acquisition request; Until receive the file data that source station is returned.
The file data receiving is sent to client by step 8:Cache server.
Realizing in process of the present invention, inventor finds to exist in prior art following technical problem:
