Referring to Fig. 2, the embodiment of the present invention provides a kind of document transmission method, and the method goes for base
Content distribution process under HTML (Hypertext Markup Language) (Hypertext transfer protocol, Http), tool
For body, the method can apply to holding of each step of caching server as shown in Figure 1, i.e. the method
Row main body can be caching server as shown in Figure 1, such as cache memory (Cache) clothes
Business device, also referred to as edge C ache server, etc..The flow process of the method is described as follows:
Step 201: caching server receives the file fragment acquisition carrying the first parameter that client sends
Request；Wherein, file fragment obtains the part data slot that request is used for asking to obtain in the first file,
First parameter is positioned at the position of the byte section in the first file, file acquisition for characterizing part data slot
The request that request cannot process for the source station server corresponding with caching server.
Wherein, the first parameter is positioned at the position of the byte section in the first file for characterizing part data slot
Put, the first parameter for example, start parameter, etc..Such as, the first file is to comprise 1-10000 byte
Video file, and the first parameter is for characterizing the data slot of 500-10000 byte in the first file, i.e.
The data slot that part data slot is the 500-10000 byte in the first file herein.
Specifically, the first parameter can be the drag operation that client end response user drags playing progress bar
And the parameter determined, such as, the playing duration of a collection TV play is 40 minutes, and this collection TV play includes
0-10000 byte, if user wishes to start viewing from the 10th minute by dragging playing progress bar, and
Assume with the 10th minute start part data slot be the 2500th byte, illustrate user wish viewing from
The video content that 2500 bytes start.
Or, the first parameter can be the predetermined broadcast strategy that stores based on client of client and determine
Parameter, such as, for TV play, the broadcast strategy that user sets is directly to skip head, and false
If head are 2 minutes, that then shows user directly to wish from 3 minutes to start to watch video.
In embodiments of the present invention, corresponding with caching server source station server is to carrying the first parameter
File fragment obtain request cannot process, say, that carry first when source station server receives
The file fragment of parameter cannot resolve from this request when obtaining request and obtain the first parameter, then naturally also
Just cannot determine that from the first file client asks the part data slot obtained according to the first parameter, with
Time respond for the request that caching server is sent, then the first complete file can be sent to
Caching server, but so and the request demand of client cannot be met.
Step 202: caching server obtains request based on file fragment, generates and obtains request with file fragment
Corresponding range request.
In order to meet the request of client to meet the actual viewing demand of user, in the embodiment of the present invention

File, and the first parameter is for characterizing in this video file as a example by the data slot of 500-10000 byte,
When source station server is when processing this range request, it may be determined that the part data of client request
Fragment is the data slot of 500-10000 byte in this video file, i.e. the part data of client request
It is 500-10000 that fragment is positioned at the position of the byte section in the first file.
In specific implementation process, first based on the first parameter, caching server can determine that range asks
Head, continues as a example by above-mentioned example, and the form of range request header is range:bytes=500-10000, its
Starting byte (range offset) is 500, and storage address size is 9500, wherein, stores address size
It is range length of an interval degree, say, that by range request header, client request can be specified
The beginning byte that is positioned in the first file of part data slot and terminate byte.
Ask it is possible to further range request header based on the first parameter determination adds file fragment acquisition to
In asking, specifically, the message header interpolation range request of request such as can be obtained at file fragment
Head, the file fragment that with the addition of range request header acquisition request being defined as please as range the most again
Ask, say, that i.e. can generate range request by file fragment acquisition request is processed.
It addition, the range request in the embodiment of the present invention can be understood as carrying the request of range,
Due to range request, there is set message format and range request can be known by source station server
Not and process, range request is generated so being obtained by the file fragment that cannot be processed by source station server
Mode, the file fragment that source station server can be allowed can be sent client obtains request to be carried out correctly
Identify, to improve the correctness of request response, meet the actual viewing demand of client user.
It addition, during the request that obtains according to file fragment generates range request, when will be based on first
After range request header determined by parameter adds in file fragment acquisition request, in order to reduce range
The data volume of request and reduction information as far as possible repeat, and can wherein corresponding with the first parameter information be deleted
Remove because this partial information can be substituted by range request header, and its for the server of source station also
Invalid, by carried out delete can with range request data volume with reduce data volume transmission,
Improve from caching server to the efficiency of transmission of source station server.
Step 203: range request is sent to source station server by caching server, so that source station server
From the first file that it stores, part data slot is determined according to range request.
After generating range request, caching server can send it to source station server, due to
Range request can be processed by source station server, and then can service from source station according to range request
Device determines, in the first file of storage, the part data slot that client is asked.
Further, source station server is in the part data slice determining that from the first file client is asked
After Duan, can by determined by part data slot be sent to caching server.
Step 204: caching server receives the part data slot that source station server sends.
Step 205: part data slot is sent to client by caching server.
It is to say, caching server is after receiving the part data slot that source station server sends,
Client can be sent it to, so that client is obtained in that part data slot and by part data slice
Section plays out in time, then the video content of broadcasting can be after user drags playing progress bar just
Position commence play out, so can meet the actual viewing demand of user, promote the viewing body of user
