generate 7 static pages on the server in advance, they can be dynamic pages, this does not affect the concept model of State transfer and the stateless features of servers.
Those with architectural design experience should be clear that compared with stateful service design, stateless services can easily achieve horizontal scaling of system performance. By adding hardware, deploying multiple stateless services and load balance will not be restricted. However, in stateful service mode, sess

slightly more accurate. I even created a little graph of the claims in this post here, that string. empty is faster. i'm too lazy to do the test myself, so if you want to verify this, knock yourself out. I do love making graphs though.
That is to say, to judge whether the string is null or not, the best method is str. Length = 0!

Using PHP to quickly query the ranking position of keywords in the search engine, the principle is very simple.
The code is as follows:

*/
$ Page = 30; // Number of pages
$ Domain = "lansj.com"; // domain name
// $ Domain = "lost63.com ";
