In the second half of 2005, in order to suppress freewap, the mobile phone number and UA were transmitted to all Monternet wap websites. But there is a problem. Many connected SP (Monternet service) need this mobile phone number and UA. What do we do? So we set a white list inside the mobile. All servers in the whitelist are treated equally with Monternet. This is the origin of the white list.
2. What is a white list and what does it do?
A white list is a list of servers, that is, all servers in the list are called white list servers. His role is to get the same treatment as Monternet business. For example, you can get the user's mobile phone number and UA.
3. What is 3.UA?
UA is the abbreviation of USER_AGENT. That is, the mobile phone model used, such as Nokia N70.
4. How did you get your mobile phone number and UA? Can you compare it with the internet?
Yes, for example, the Internet:
If a user visits a page on the Internet, the Internet page can easily get relevant information about the user, such as what operating system the user uses, the screen size used and so on.
Similarly, if a mobile phone user visits a free wap, the wap page can also get the relevant information of the user, but the mobile phone number and UA are now closed. So that users can't get the most important information of users.
5. Which companies have white lists now?
This article is actually very simple. Just look at the wap websites of these companies. For example, if we go to wap.qq.com, we can clearly see your mobile phone model on his homepage, so Tencent will definitely get the white list.
In this way, we can get the white list from Tencent, Sina, Air and Tom. Others like Baidu and Sohu are not on the white list.
6. Can ordinary free ap websites be whitelisted?
It's hard. Almost impossible. It is rumored that if you enter the white list, you need to move the boss's signature now.
7. Do foreign operators do the same?
As far as I know, foreign operators have not done so, which may be related to the monopoly of domestic operators.
8. Is there a similar situation in China Unicom?
Because Unicom has always kept the mobile phone number and UA secret. I wonder if there is a similar whitelist system?
9, the benefits of entering the white list
There are three main points.
A, can get the user's mobile phone number, which is very important and is the basis of precision marketing. For example, if a user visits a travel webpage, we can define this user as a travel user. Reverse marketing it.
B, you can get the mobile phone model, which is convenient for users to use. For example, mobile games, if you know the user's mobile phone model, it is easy for the website to promote its suitable mobile phone model.
C, the mobile executives made it clear at the internal meeting that the whitelisted enterprise China Mobile guaranteed its access quality.
