How to set ajax timeout (an action is executed twice)

An action was executed twice. This operation took more than 5 minutes to complete, so I searched for a few places where I can set the timeout. I hope it will be helpful to everyone.

I found it while testing the project today. An action was executed twice. This operation took more than 5 minutes to complete. The engineering environment was apache2+tomcat6.0.

Online search found several places where timeout can be set:

1.ajax syntax to set the unit milliseconds, for example:

$.ajax({ url: XXX, timeout: 600000, type: 'POST', data: { }, error: function() { show_fail_meg("启动系统失败 ！"); } });

2.tomcat configuration server.xml in milliseconds

Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/>

3.apache configuration file httpd.conf in seconds

# # Timeout: The number of seconds before receives and sends time out. # Timeout 60

After modifying the above several places, it was found that it still did not take effect. Finally, it was located in the mod_jk module.

mod_jk, referred to as JK, is the Apache server A pluggable module that provides Apache or IIS servers with the ability to process JSP/Servlets.

That is to say, the settings of JK may cover the settings of apache2, tomcat and ajax.

The content of JK’s configuration file/etc/httpd/conf/workers.properties is as follows:

worker.master.socket_timeout=300

Sure enough, I saw that this number is exactly 5 minutes, which is consistent with the abnormal phenomenon. After changing the size and restarting, it is normal!

The above is all the content of this article, I hope it will be helpful to everyone!
