Chapter 24. Apache HTTP Server Configuration
If you uncheck the Allow Persistent Connections option, the
If you check it, the
KeepAlive
set to the number that is selected as the Timeout for next Connection value. This directive sets
the number of seconds your server waits for a subsequent request, after a request has been served,
before it closes the connection. Once a request has been received, the Connection Timeout value
applies instead.
Setting the Persistent Connections to a high value may cause the server to slow down, depending
on how many users are trying to connect to it. The higher the number, the more server processes are
waiting for another connection from the last client that connected to it.

24.6. Saving Your Settings

If you do not want to save your Apache HTTP Server configuration settings, click the Cancel button
in the bottom right corner of the HTTP Configuration Tool window. You are prompted to confirm this
decision. If you click Yes to confirm this choice, your settings are not saved.
If you want to save your Apache HTTP Server configuration settings, click the OK button in the
bottom right corner of the HTTP Configuration Tool window. A dialog window appears. If you answer
Yes, your settings are saved in /etc/httpd/conf/httpd.conf. Remember that your original
configuration file is overwritten with your new settings.
If this is the first time that you have used the HTTP Configuration Tool, a dialog window appears,
warning you that the configuration file has been manually modified. If the HTTP Configuration Tool
detects that the httpd.conf configuration file has been manually modified, it saves the manually
modified file as /etc/httpd/conf/httpd.conf.bak.
Important
After saving your settings, you must restart the httpd daemon with the command
service httpd restart. You must be logged in as root to execute this command.
