Three methods for generating static HTML pages on the aspx page

Asp tutorial x: three methods for generating static HTML pages
 
In the asp.net tutorial system, some dynamic pages are frequently used, such as our homepage index. aspx involves a lot of database tutorial queries. When there are users, the server constantly queries the database and actually does a lot of repetitive work.

MyPage. aspx on the server side

Customer terminal display mypage.htm

Client

To address this waste of resources, we are now designing a solution. First, we will not change the content for a period of time, but the static pages generated by a large number of dynamic pages will be stored on the server. When the client sends a request, let them directly generate the static page, as shown in the process.

Customer terminal display mypage.htm

Client

Execute

MyPage. aspx on the server side

Mypage.htm at the server end

Now we need a background program to complete these tasks.

We can make this a class classAspxToHtml and its code
