China Mobile two access points cmwap and cmnet

            


China Mobile's mobile Internet has two gateways are cmwap and cmnet, on the difference between the two gateway services to the Internet can search for a lot of relevant information, there is no longer a burden. Today would say is the difference between the two technologies.

It can be run cmnet, it is to run a group of sock proxy server, you can use any communication protocol to connect to a server on the Internet on the Internet through the proxy server, of course, including the most important HTTP. cmwap is different, it is a set of software running the WAP gateway proxy server, but it is only open HTTP (S) protocol, you can use any of the communication ports. Costs due to similarly configured servers if only proxy HTTP protocol, then the number of users it can load much higher than the proxy cmnet any Internet protocol gateway, which is why the same Internet access point to select cmnet reasons to be much higher .

When moving the gateway before sending their phone number and UA, through cmnet is unable to get to the phone number. The same is true today, some of the SP or the portal can get access to the site's user's mobile phone number via cmwap access point, but you can not get the time if the user chooses cmnet access point. It is also China Mobile in mind when planning the two access points.

But today's various cmwap access points WAP gateway proxy software, there are many problems, one of the developers of the site's most troublesome problem is the cookie handling. Because many low-end mobile phone browser does not support cookie, so WAP gateway meddle assume this task - the gateway software allows these phones support cookie, this arrogation behavior causes WAP site developers at a loss, in particular in:

1. phone still access the site after clearing cookie cookie
2. cookie will somehow be lost or generate
3. Repeat the cookie leads to generate illegal request Header

There should be a lot of very small problems make developers headaches. Mechanism to run properly on the Internet over the WAP will have this kind of problems, which focus more on user login, access control and other aspects. Of course, at this time also came up with a lot of WAP sites countermeasures, but after all, is neither fish nor fowl or many loopholes. These problems only occur when using cmwap access point, because it managed to do too much, the tube pipe, the pipe should also have control, so no problem that would be strange.
