1. Introduction
It has been 50 years since the birth of the first remote control robot in the world. In just a few years
With the development of theories and the needs of industrial production and the advancement of related technologies, robotics have gone through three generations [1]: (1) programmable display
Teach reproduction robots; (2) control robots with certain autonomous capabilities based on sens
Abstract: High-Performance Network robots are the core of the new generation of Web intelligent search engines. Whether they are efficient directly affects the performance of search engines. The key technologies and algorithms involved in the development of high-performance network robots are analyzed in detail. Finally, the key program classes are given to help the actual application and development of the

If you think the page on the site * should * be open to any Internet user, then 401 of the information indicates a deeper problem. First, you can check your URL through a browser. The browser should run on a computer that you have never used before, and that does not contain any information about you, and you should also avoid using the authentication (password, etc.) you have used before.

your Web site uses the session ID in the URL.
If your Web page uses the session ID, you cannot put ads on those pages. Because each time a different user view the page, this session ID will change, resulting in the Web site changes, so this URL will not appear in the index, but into the queue to be crawled. When crawling to this site, the session is likely to have been terminated. This causes the Web page that the user sees to always fail to en
1. What is robots.txt?
Robots.txt is a plain text file for website and search engine protocols. When a search engine spider comes to visit the site, it first crawls to check if there is a robots.txt in the root directory of the site,
If it exists, the access is determined according to the contents of the file, and if not, the spider crawls along the link. Robots.txt is placed in the root directory of the project.
