After introducing pseudo-static, I will add two more nouns to parse static URLs: pure static HTML document, you can use filetype:htm QueryThe web page reached, dynamic URL: the content is stored in the database, and the content is displayed according to the requirements. The URL ends with? # & Display different parameters, such as: news.php? lang=cn&class=1&id=2

Pseudo-static is relative to real static.
1. What is static technology?
The so-called static means that there is no question mark in the address.
2. Why use pseudo-static technology?
One of the biggest features of Web applications is statelessness. When one page jumps to another page, all parameters on this page will be discarded. Therefore, dynamic pages generally use URL addresses to save their parameters. Like:
www.attjs.net/essay.asp?id=1
In this way, when the search engine admits this page, it may enter an endless loop because of the question mark (previously Dongwang There is such a loophole that spiders cannot get in), so in many cases addresses with question marks will not get in, which reduces the efficiency of page collection.
In this case, wouldn’t choosing a URL without a question mark make it easier for search engines to index your own web pages? indeed. The URL of a static web page happens to not have a question mark, so we have to fake it for the sake of SEO and improve the efficiency of website inclusion.
1. About the use of pseudo-static
Some users think that the actual number of included posts between pseudo-static and true static will be very different. In fact, this is not the case. From your personal perspective, you can judge whether a post is truly static or not. Pseudo-static?
It is probably difficult to see, because the so-called static means that there is no question mark in the address. The address without question mark is static. Does it matter whether it is real or fake? Can the search engine see it? So? , in fact, whether it is real or fake, it is the same for search engines. The search engine did not say that you are fake and I will not include you.
In the final analysis, why search Will the engine not include URLs with question marks? Because search engines are afraid of entering an endless loop due to question marks, so many times addresses with question marks will not be included. For search engines, pseudo-static is actually static because there is no URL in the address. Question mark, so there is no saying that true static is included more than pseudo static.
2. About the disadvantages of pseudo static
Of course, as the author of an article said, "If the traffic is slightly larger and pseudo static is used, the CPU will appear When using overload, my system crashed when more than 300 people were online at the same time, but when I did not use pseudo-static, even when more than 500 people were online at the same time, my ISS number was 1000. This is indeed the case, because pseudo-static is judged by regular rules. Instead of the real address, the responsibility for determining which page to display is transferred from direct specification to the CPU. Therefore, the increase in CPU usage is indeed the biggest drawback of pseudo-static.
Summary
  1. Use true static The method can be directly eliminated, because no matter how it is generated, it will be very harmful to the hard disk. ​
​ 2. Since the effect of true and false static is the same, we can choose pseudo static. ​
​ 3. But fake static Extensive use of static will cause CPU overload. ​
​ 4. So we only need to not use it in large quantities. ​
​ 5. Since static is only for SEO to see, we only need to use pseudo-static for SEO, and there is no need to give it. User use.   
  6. So we only need to use pseudo-static in the Archiver specially provided for SEO crawling
