What should I pay attention to when using HTTP?

In order to avoid the problem of IP blocking during the crawler work, HTTP is generally used. Using HTTP may encounter some sudden problems. In order to reduce the occurrence of such problems, the following are some matters that need attention:

1. IP security

There are many factors that affect the development of the website, one of which is the security of the IP address. If the IP used has been restricted or there are some bad content on the IP website, it is easy to be implicated, so when using the IP replacement tool, if the IP changes, it must ensure security.

2. Data backup website

If the user chooses to establish a website construction server, then the IP replacement tool is a necessary condition to ensure security. Although the server does not need to be restarted when changing the IP, there is a certain possibility of data corruption.

3. Replace IP when the website traffic is low

During the process of changing the IP, the URL may not be opened. This is because the server re-analyzes the IP. For servers with large traffic, you can choose a relatively small traffic period to replace it to reduce the possible impact.
