In the embodiment of the invention; Owing to only send a HTTP request; Therefore avoided being redirected of HTTP request in the prior art, and because the redirected of HTTP request can change the client explicit address; Do not have being redirected of HTTP request will avoid changing the client explicit address, the network address that shows in the address field of client after promptly information pushes can not change.

The embodiment of the invention three provides a kind of information-pushing method, and is as shown in Figure 4, may further comprise the steps:

Step 401 after the DNS request package that receives the client transmission, parses the domain name that client is wanted accession page from this DNS request package.Wherein, gathering the DNS request package can be chosen in the place that network traffics such as metropolitan area network gateway concentrate and carry out.

Wherein, the structure of DNS packet is as shown in Figure 5, comprising:

The most preceding 2 bytes (16bit) of ID:DNS packet are this mutual sequence numbers of sign, and request package is corresponding with respond packet.

FLAGS: flag bit, the 3rd, 4 byte of the packet of DNS (standard queries is 0x0100, and normal response is 0x8180).

The Queries:16 bit field is used for problem definition recording mechanism partly, the number of record problem.

The Answers:16 bit field is used to define the resource record number of answering part, the number of recording responses.

Authority RRs:16 bit field is used for the resource record number of definition command part dns server, the number of record authorization server.

Additional RRs:16 bit field is used to define the resource record number of addition record part.

In the structure of above-mentioned DNS packet, first row is the reference line of the shared bit of data, fix from three line lengths that ID begins, and 12 bytes in position altogether, but QUERIES (inquiry) must have indefinite length (follow through inquiry domain name relevant); Answers, Authority RRs, Additional RRs are optional.

Request package in the DNS packet is corresponding with the source target MAC (Media Access Control) address of respond packet, and purpose IP address, source is corresponding, and the source destination interface is corresponding.

Step 402 is returned the DNS response to client, the IP address of carrying Information Push Server in this DNS response; The IP address of said Information Push Server is different with the IP address of first server.

Wherein, send before the response, need structure DNS respond packet, several steps below main the branch:

1, the packet bottom field that setting will be constructed according to the DNS request package: the source target MAC (Media Access Control) address exchanges, and purpose IP address, source exchanges, and the source destination interface exchanges;

2, the ID of DNS equals the ID of request package;

3, be provided with as follows: Questions=1, Answers=1, Authority RRs=0, AdditionalRRs=0;

4, the Queries of request package is copied to the packet of neotectonics;

5, consistent among structure Answers territory: the Name=0xc00c, Type and class and Queries, TTL=30, Data length=4, the IP of addr=WEB Information Push Server (having inserted the IP202.108.22.43 of Baidu in order to demonstrate effect here);

6, calculate IP, the UDP verification with, accomplish the respond packet structure.

Step 403; Client is only sent the HTTP request to Information Push Server after receiving this DNS response, rather than wants the requested service device to send the HTTP request originally to it; And only can send a HTTP request, thereby avoid Information Push Server and former request server all to return response.

After client was received the DNS response, client thought that the IP address in the DNS bag is exactly the homepage IP address that will visit, can send request with the IP address in the DNS bag.So, only can send a request to this IP, and, the network address of still importing in the address field for the user.

Afterstep 404, Information Push Server receive this HTTP request, send to client and to push the page, client is received and in browser, is shown after the http response of Information Push Server and push the page.

Such as; A client has been sent the DNS request in order to visit Google; Return to DNS response of client before the dns server if get the jump on, and be the IP address setting that inquiry is returned the IP of Baidu's server, what client finally showed will be Baidu's page.Wherein, Baidu's server is equivalent to Information Push Server, and the page that demonstrates is equivalent to push the page, remains www.google.com in the address field.
