As it is shown in figure 1, embodiments of the invention one provide the processing method of a kind of network data request, including following step
Rapid:
S101, generation initial http request message, comprise request row and request header in initial http request message, at request row
URL(unified resource location) in be target domain name, Host field is positioned in request header；
S102, in the dns cache inquiry target domain name and the ip address of binding thereof；
If S103 finds the ip address of target domain name and binding thereof in the dns cache, then by initial http request message
The target domain name of URL replaces to the ip address of its binding, and bound targets in the Host field in initial http request message
Domain name, seals into secondary http request message up for safekeeping, utilizes its ip address bound to set up a socket with web server and is connected,
Secondary http request message is sent to web server after；Walk around the LocalDNS server of ISP, by ip address directly with
Web server connects, and substantially can ensure that DNS is not held as a hostage, it is ensured that absolute safety；
But, if the most not finding the ip address of target domain name and binding thereof, still it is intent on by reliably
Ip address directly is set up with web server to be connected, it is necessary to by PublicDNS server or domain name resolution agent service
Device carries out domain name mapping, and PublicDNS server refers to that 114DNS, OpenDNS, Google PublicDNS etc. is this credible
Spending higher dns server, domain name resolution agent server refers to provide the HttpDNS private server of service, and client makes
Make requests on to 80 ports of HttpDNS server with http protocol, replace traditional DNS Protocol 53 ends to dns server
Mouthful make requests on, got around the Local DNS of operator, thus avoid the abduction using operator Local DNS to cause and
Inter-network problem；It can thus be seen that when client's request data, if to carry out above-mentioned domain name mapping, that client gives visitor
The reflection at family is stagnated exactly, this directly reduces the performance of browser, so the strategy used in the present embodiment is directly will just
Beginning http request message sends to the LocalDNS server of ISP, keeps client to have a response speed faster, meanwhile,
Generate first object domain name mapping request message based on DNS Protocol, first object domain name mapping request message comprises target
Domain name, sends the first domain name mapping request message to PublicDNS server, then receives PublicDNS server and returns
The first domain name mapping response message, finally obtain be included in the first domain name mapping response message web server ip ground
Location, and ip address and the binding of target domain name of web server are stored in DNS cache, for next time for same domain name
Http request；Above technical scheme is not to improve safety simply and stop the probability that DNS kidnaps, but in safety
With accomplish higher balance in customer experience, ensureing that browser possesses faster on the premise of reflection speed, reducing as far as possible
The probability that DNS kidnaps；From the point of view of for common customer, the frequency changing network environment is the highest, and conventional website is also taught
It is fixing, so when the amount of storage in DNS cache is the most, and the probability of the LocalDNS server walking around ISP is the highest, then
The request needing the LocalDNS server process of ISP will be little, and the LocalDNS server of ISP is also selectively to rob
Holding the DNS of user, in the situation that request amount is little, the actual DNS occurred kidnaps will be little, so the request of this network data
Processing method be a kind of safety and ensure the method that customer experience has both.

S304, arranging benchmark life span for each domain name in DNS cache, benchmark life span is set to 600s；
S306, when the web server in the first domain name mapping response message or the second domain name mapping response message ip address with
The ip address of leaving a question open of web server is inconsistent, then the ip address of leaving a question open of the web server in DNS cache is replaced to the first territory
The ip address of the web server in name analysis response message or the second domain name mapping response message, and on the basis of life span
Upper is that this target domain name increases extra life span, and extra life span is set to 300s, as it is assumed that the first domain name mapping response
The ip address of the web server in message or the second domain name mapping response message is more reliable, so when leaving a question open ip address
With they inconsistent time, illustrate that DNS is kidnapped by the LocalDNS server of ISP, the ip address of leaving a question open in DNS cache is by reliably
Ip address is replaced, it is contemplated that the LocalDNS server of ISP has carried out DNS abduction to this domain name, the possibility the most again kidnapped
Property higher, so improving the life span of domain name after replacing, improve safety period for this domain name.
S307, when the web server in the first domain name mapping response message or the second domain name mapping response message ip ground
Location is inconsistent with the ip address of leaving a question open of web server, then it is assumed that the LocalDNS server of ISP is to the process of this target domain name not
Credible, upper once for the http request of this target domain name time, if the most do not find this target domain name and
The ip address of binding, first passes through PublicDNS server or the ip ground of domain name resolution agent server acquirement web server
Location, then replaces to the ip ground of this web server by this target domain name that the unified resource in initial http request message positions
