Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear
Chu, it is fully described by.
Fig. 1 is a kind of connected mode schematic diagram of Web caching servers in the prior art.As shown in figure 1,
Terminal 101, Web caching servers 102 and external network server 103 are connected with interchanger 104.Its
In, terminal 101 is with Web caching servers 102 under same LAN, and Web caching servers 102 are
The internet information that the terminal that is stored with 101 is often accessed.Under normal circumstances, terminal 101 is accessing internet
When, the message that request accesses internet is sent by external network server 103.Web caching servers 102
The up-link exported by operator is monitored in real time to terminal 101, if Web caching servers 102
Detect terminal 101 to ask to access the message of internet by external network server 103, for example, sent out to internet
Play download request, using redirecting technique, such as redirecting techniques of HTTP 302, guiding terminal 101 to
The request of Web caching servers 102 needs the content accessed so that terminal 101 is without passing through external network server
103 access internet, you can obtain the content for needing to access.
It can be seen that the localization that the setting of Web caching servers 102 realizes internet hot spots content is deposited
Storage, reduces the time delay of terminal access internet content in LAN.Because Web caching servers 102 are adopted
Realize that customer flow is guided with redirecting technique, thereby it is ensured that it is to ensure that Web delays to be redirected to power index
Deposit the key of the stable operation of server 102.And in the prior art, because Web caching servers prestore file

Embodiment one
Fig. 2 is the schematic flow sheet one of reorientation method provided in an embodiment of the present invention, with reference to shown in Fig. 2,
This method can include：
Step 201：Terminal sends the request message of n times first to external network server, wherein, N is more than or equal to
1, the first request message is used for terminal and accesses data from external network server request first；
Wherein, first the data that data, i.e. terminal are expected to obtain from internet using external network server are accessed.
In actual applications, the form of the first request message is including a variety of, for example, the lattice of the first request message
Formula can be：
GET/HTTP/1.1
Accept:text/html.application/xhtml+xml.*/*
X-HttpWatch-RID:53811-1005
Accept-Language:en-US
Rser-Agent:Mozilla/5.0(compatible；MSIE 10.0；Windows NT
6.1；WOW64；Trident/7.0)
Accept-Encoding:gzip,deflate
Host:www.baidu.com
DNT:1
Connection:Keep-Alive
Cookie:H_PS_PSSID=16669_16716_1433_14601_17155_12657_12824_1286
7_16938_17000
Certainly, the first request message format also includes extended formatting, and the embodiment of the present invention is to the first request message
Form be not particularly limited.
You need to add is that, to ensure that the first request message sent during terminal test to external network server can
Go out net from operator's outbound, it is necessary to send the request message of n times first, such as 10 to external network server
It is secondary, 100, it is 1000 inferior, so as to ensure the accuracy that terminal analysis is redirected.
Preferably, terminal by transmission control protocol (TCP, Transfer Control Protocol) set up with
The connection of external network server；And connected using TCP to external network server the first request message of transmission, wherein,
First request message is asked including HTTP (HTTP, Hyper Text Transfer Protocol).
Step 202：Terminal receives the M secondary response information that Web caching servers are sent, wherein, M is more than
Equal to 1, response message is corresponding with the first request message；
Wherein, response message, including head response (Response Header) information, response text message etc.,
First is obtained from Web caching servers for guiding terminal and access data, that is, be redirected to Web caching clothes
Business device.For example, in practical application, response message includes HTTP 302 and redirects bag, wherein, 302 reset
To i.e. 302 redirect are represented and temporarily redirected (temporary redirect) packet.
In actual applications, Web caching servers can in real time be monitored to the message that terminal is sent.Eventually
End sends the first request message, Web when needing to obtain the first access data from internet to external network server
Caching server can return to response message when monitoring terminal the first request message of transmission to terminal, so as to
Terminal is redirected to Web caching servers.
It is to be appreciated that terminal is after the TCP connections of disconnection and external network server, could be slow with Web
Deposit server to be attached, and receive the response message of Web caching servers transmission.
Step 203：Terminal parses response header according to each response message；
Through actual measurement, if the complete response message that terminal parsing Web caching servers are sent, is generally needed
Want 2 minutes or so；If terminal only parses the response header in the response message of Web caching servers transmission,
It is usually only necessary to 0.1 second or so, so, substantially increases the time that terminal redirects test.
Step 204：Terminal is redirected to Web caching servers according to each response header.
It is to be appreciated that response message includes response header, response text message etc., and in response message
Head response information include terminal redirect test needed for information, such as destination address, conditional code,
Therefore, the head response in the response message that terminal is only sent to Web caching servers is parsed, without
Whole response text in resolution response information is whole file data, it is possible to realize that terminal redirects test.
Consequently, it is possible to be far smaller than the size of response message due to responding the size of header so that terminal parsing rings
The time of information is answered to greatly reduce, while avoiding terminal largely tests the stream brought to Web caching servers
Measure pressure.
Exemplarily, head response information includes destination address and conditional code, correspondingly, and terminal is rung according to each
Answer header to be redirected to Web caching servers, specifically include：Terminal is identifying that each destination address refers to
During to Web caching servers, terminal is completed according to destination address and conditional code and is redirected to Web caching clothes
Business device.
In actual applications, conditional code is used for the mark for characterizing the passage that terminal is redirected to Web caching servers
Know, terminal receives conditional code, that is, illustrate that terminal needs to be redirected to Web caching servers, and destination address
That is the address of Web caching servers, therefore, terminal can complete terminal weight according to destination address and conditional code
It is directed to Web caching servers.
You need to add is that, the information needed for when destination address is redirected for terminal is generally carried in sound
Answer address (Location) field in header.For example, if response header is：
HTTP/1.1302Moved Temporarily
Date:Wed,02Sep 201509:27:59GMT
Content-Type:text/html
Content-Length:215
Connection:Keep-Alive
Location:heeps://www.baidu.com/
Server:BWS/1.1
X-UA-Compatible:IE=Edge, chrome=1
Set-cookie:DB_LAST_QID=13201064592551329076；Path=/；Max-Age=1

</body>
</html>
Wherein, the location field in response header is：Location：https://www.baidu.com/,
So, the destination address that terminal redirects test is：https://www.baidu.com/。
Understandably, if destination address points to Web caching servers, illustrate that Web caching servers are pre-
The terminal that is first stored with expects the data obtained；If destination address is not directed to Web caching servers, illustrate
Web caching servers do not prestore the data that terminal is expected to obtain.

Step 205：Terminal sends N and M to Web caching servers, so as to Web caching servers
The power that is redirected to that Web caching servers are redirected to terminal is detected.
Understandably, because N is the number of times that terminal sends the first request message to external network server, M is eventually
End receives the number of times that Web caching servers send response message, therefore, and terminal sends M and N to Web
Caching server, is redirected so that Web caching servers obtain terminal by calculating M and N ratio
Power is redirected to Web caching servers, so as to realize the redirection function of analysing terminal.
Further, with reference to shown in Fig. 4, step 206 and step 207 are also included after step 204,
Specially：
Step 206：Terminal sends the second request message to Web caching servers, wherein, the second request disappears
Ceasing is used for terminal from Web caching servers request the first access data；
Step 207：Terminal receives the first access data that Web caching servers are sent.
It should be noted that terminal is after realization is redirected to Web caching servers, Web can be passed through
Caching server asks the first access data, without the data obtained using external network server from internet,
So, the time delay of terminal access internet content in LAN is reduced.
Understandably, terminal is after the first access data are obtained, it is possible to use first, which accesses data, carries out institute
The data service or communication service needed.
