Sixth embodiment of the invention, the present embodiment are on the basis of the above embodiments, a sheet to be introduced in conjunction with attached drawing 5
The application example of invention.
Existing technology is easy to be influenced by browser rs cache, and user is caused to be beaten during accessing outer net
The page is not opened, or opens the scene of the wrong page.Specifically, under the influence of existing browser rs cache, work as not closing
In the case of preceding browser, browser can cache the IP address, after the networking state switching of wireless routing device, successive field
Name access request will not quickly retransmit DNS request, but directly initiate TCP (Transmission with the IP of the caching
Control Protocol, transmission control protocol) three-way handshake, the page being susceptible in this way before resting on can not open
The phenomenon that correct page.
The embodiment of the present invention can overcome the problems, such as above-mentioned, monitor the internet behavior of user in real time and start corresponding
Iptables routing forwarding rules so that for wireless routing device whether in the state of failed cluster or networking, access is wireless
The user of routing device will not be influenced using the browser access page by browser rs cache.Using the embodiment of the present invention
Technical solution after, the internet behavior of user is monitored by wireless routing device dynamic, is not only restricted to the influence of browser rs cache,
The user of access wireless routing device can access the correct page, promote user experience.
As shown in figure 5, the flow that the present embodiment HTTP redirection executes, as follows：
Step S1：Wireless routing device detects this equipment networking state, and routing forwarding rule are initialized according to networking state
Then, add or delete corresponding redirection forward rule.If failed cluster thens follow the steps S2, step S3, step S4, this portion
Divide the technical solution under the not connected interconnection net state corresponding to first embodiment.If networking thens follow the steps S5, step S6,
Step S7, this part correspond to the technical solution of second embodiment having connected under interconnection net state.
Step S2：Routing rule is initialized if current wireless routing device failed cluster, removes the routing added when networking
Forward rule is redirected, according to the state of current wireless routing device failed cluster, notice kernel opens HTTP redirection gateway work(
Can, and the HTTP request message redirecting that all purposes port is 80 ports is arrived into gateway address, it is step S3 simulation completion
TCP three-way handshake is laid the groundwork.Three-way handshake between subsequent terminal side browser and virtual ip address is browser and nothing actually
Interaction between line routing device, because only that after shaking hands successfully, browser can just issue the GET request message of HTTP, just
The GET request message of the HTTP of intercepting and capturing is handled in step S4.
Step S3：Whether monitoring currently receives the DNS request that browser is directed to outer net domain name, and one is returned if receiving
The virtual ip address that dynamic random generates, if directly carrying out TCP three-way handshake when browser is sent based on virtual ip address.
Step S4：The HTTP GET that destination interface is 80 are intercepted and captured by the hook Hook Functions of (SuSE) Linux OS kernel
Request message, by the way of the conditional code of feedback HTTP 302, simulation dns server sets up the response of a HTTP 302
Gateway address is filled into location field so that browser is jumped to again in the URL of gateway by message.
Step S5：Routing rule is initialized if current wireless routing equipment networking, is redirected before networking is removed after networking
To the rule of gateway address.
Step S6：(SuSE) Linux OS kernel is notified to close HTTP redirection gateway function according to networking state, and will
All messages that the hook Hook Functions of (SuSE) Linux OS kernel obtain are let pass, without any processing.
Step S7：Wireless routing device resolves to the outer net domain name that browser access before networking is crossed corresponding true successively
Real IP address, outer net domain name, virtual ip address, real IP address just have unique correspondence at this time.If there are outer domains
Name parsing failure then preferably traverses the domain name of these parsing failures, legitimacy detection is first carried out, for legal
Domain name gives the chance of DNS name resolution three times, the acquisition of the guarantee real IP address of bigger probability again.Finally addition is virtual
Redirection of router forward rule under the corresponding real IP address of IP address prevents because the influence of browser rs cache can not be just
Often open user's page to be accessed.
In embodiments of the present invention, (SuSE) Linux OS provides the work(that powerful routing forwarding and data flow are intercepted and captured
Can, the message technology of HTTP is intercepted and captured with hook in conjunction with solving the problems, such as that the caching of browser DNS causes with routing forwarding,
Redirecting agreement and realize corresponding redirection function by redirection of router forward rule and HTTP.
In the state of wireless routing device failed cluster, corresponding redirection forward rule is added, is forced all purposes
Port is that the HTTP request of 80 ports is redirected to gateway, simulates the TCP three-way handshakes of all HTTP requests.If in Shipping Options Page
When inputting some outer net domain name in interior address field, wireless routing device finds that network disconnects at this time, will return to one virtually
IP address is to browser, and this virtual ip address is that dynamic random generates, corresponding to each outer net domain name of browser access
Virtual ip address it is different, but be private network IP address.Browser server corresponding with this virtual ip address is led to
It is reliable, it is that browser and wireless routing device are communicated, after completing TCP three-way handshake, in (SuSE) Linux OS kernel
Face hangs a hook Hook Function, for monitoring the request message for intercepting and capturing HTTP, and using the conditional code of feedback HTTP 302
Mode so that the browser is redirected on the gateway page.
After wireless routing device networking, each domain name accessed before networking is resolved into the website successively and is corresponded to really
IP address, outer net domain name, virtual ip address, real IP address just have unique correspondence at this time.It adds again simultaneously corresponding
Redirection forward rule, the HTTP request for accessing virtual ip address is redirected to real IP address.And monitor solution in real time
If analysis is as a result, because the factors such as network signal intensity and DNS server low-responses lead to some in wireless routing device after networking
Outer net domain name fails to obtain true IP address, and carrying out dns resolution again to domain name in addition at this time obtains real IP address,
Corresponding redirection forward rule is added, ensures that the HTTP request for accessing virtual ip address is redirected to real IP address.Ensure
When the user of access wireless routing device can toggle under wireless routing device unconnected state and networking state, as long as
Do not close current browser, so that it may not influenced by browser rs cache IP；It will not quickly be re-initiated in browser new
In the case of DNS request, browser still can correctly show user's outer web page to be accessed.
Seventh embodiment of the invention, what is stored and executed in the computer storage media of the present embodiment asks weight to HTTP
The flow of orientation with first or two embodiment it is identical.In Project Realization, the present embodiment can add required general hard by software
The mode of part platform is realized, naturally it is also possible to which by hardware, but the former is more preferably embodiment in many cases.It is based on
Such understanding, the flow that HTTP request of the invention redirects can embody in form of a computer software product, should
Computer software product is stored in a computer storage media (such as ROM/RAM, magnetic disc, CD), including some instructions are used
So that the HTTP request that an equipment (can be the network equipments such as wireless router) executes the embodiment of the present invention redirects
Flow.
By the explanation of specific implementation mode, the technological means that predetermined purpose is taken should can be reached to the present invention
And effect be able to more deeply and it is specific understand, however appended diagram is only to provide reference and description and is used, and is not used for pair
