After why my Ajax submitted successfully, 30 minutes later again automatically s

With the jQuery Ajax through the get request is sent to a PHP, PHP will be responsible for the data into the database.
Everything is normal, but after some of the messages into the database for 30 minutes, the database will once again the message into a second time.
Many of the Internet, have seen a lot of information in English, always cannot find a reason.
Strange is, two times the same message always is exactly 30 minutes.
Do not know if there are no heroes who encountered this problem?

Could you use the server web
<session-config> <session-timeout>30</session-timeout> </session-config>
No change in 30 minutes, so your session failure, and you use the jQuery Ajax request to send an PHP request is associated with the session through get
