The URL (URL) you requested could not be obtained, but the server repeatedly received two commits
After the form submits the data, execute the PHP code (constantly insert records into the database, such as 1000 records).
But sometimes it turns out that the data record is 2000, half the number.
Then I wrote the log at the end of the execution, found that there are often two logs, separated by about 100 seconds.
Which means it's been requested two times? But the front-end was really only requested once during the test.

1, may be related to your server configuration. Because you have hidden the URL, you cannot determine whether this is the reason (if it is not a professional configuration, the probability is at least 80%)
2, may be related to your browser, if it is IE8 and below. The post form is approximately 50% more likely to be processed repeatedly
3, may be related to your program, thousands of data processing is very time-consuming, the program may time out.
4, may be related to the data itself, if you do not check the legality of the data, then the wrong data will inevitably lead to system crashes
