After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, you need to make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all these have been successfully completed, CDN can be used normally. Many users have a question, which is often asked, that is, it is necessary to put on record before they can use CDN. Today we will discuss the use of CDN without filing.

What kind of cdn is not on record? The basic nodes of license-free CDN acceleration are overseas. If you use overseas CDN, you do not need to file a record, but if you use a domestic CDN, you must put your domain name on record.

CDN involves caching technology in the server, so if it is domestic CDN acceleration, it needs to be filed in advance; but if it is overseas CDN acceleration, it does not need to be registered. Therefore, it is called license-free CDN acceleration.

According to the regulations of the Ministry of Industry and Information Technology, domestic CDN must be put on record before it can be used, so there are websites that cannot be put on record and need CDN acceleration, so you can consider using foreign CDN tools to accelerate. Can also use the domestic CDN service provider's international CDN service, the principle is still foreign CDN, only through the domestic agent way.

Foreign CDN acceleration, domain name resolution is the overseas server IP, using overseas CDN nodes, so there will be a certain risk of being blocked. Or use Hong Kong's CDN acceleration service, which is relatively more stable, has low risk of being blocked, and has little impact on access speed.

There is no need for filing to use overseas acceleration, but it should be noted that overseas acceleration platform GCD for origin-pull access to data within Chinese mainland, or Chinese mainland users to access overseas nodes must be through the network of public operators, and the speed may not be ideal, or even inaccessible. It is recommended that you can use the URL prefetch feature of overseas accelerated GCD to cache hot files in advance.

The above is about the cdn introduction that does not put on record. The virtual host of the website can enjoy Baidu's massive CDN node resources for free, rich node resources, covering the whole world, and providing acceleration services for a large number of users with unlimited traffic.
