The difference between domain names and ip access
- ip access to a corresponding server of a station is determined;
- Ip domain names on the basis of equivalent access on to do a reverse proxy function of the middle. For example: Baidu, many people will use, if you are using the same server, the server expected to carry live, if access is the domain name, the middle of the reverse proxy, users can be reverse proxy to a different server, reduce server stress.
Access by domain name, the general will do the process the user's request, such as identification, filtering effect, allowing only conform to the rules of ip access, and the rest will be filtered out. But if you know the exact ip server, it is possible to avoid this problem (of course, this is set to appear in a secure server imperfect circumstances), the successful access to the server (see follow-up can not be successful server settings, mostly It will be pass out).
