Setting Persistent Connections for the Web Server
You can set up your web server to respond to multiple requests from a client
computer without closing the connection each time. Repeatedly opening and closing
connections isn’t ecient and decreases performance.
Most browsers request a persistent connection from the server, and the server keeps
the connection open until the browser closes the connection. This means the browser
is using a connection even when no information is being transferred. The Apache
documentation refers to persistent connects as Keep-Alive connections.
You can authorize more persistent connections—and avoid sending a Server Busy
message to other users—by increasing the number of authorized persistent connections.
Important: Persistent connections are not compatible with the performance cache.
To set the number of persistent connections:
1 Open Server Admin and connect to the server.
2 Click the triangle at the left of the server.
The list of services appears.
3 From the expanded Servers list, select Web.
4 Click Settings, then click General.
5 Select the “Allow Persistent Connections” checkbox if it is not selected.
6 Enter a number in the “Maximum allowed request” eld.
The range for maximum allowed request is 1 to 2,048. The default is 500 per connection.
7 Click Save.
Web service restarts when you save the changes.
Setting a Connection Timeout Interval
You can specify a time period after which the server can drop a connection that is inactive.
To set the connection timeout interval:
1 Open Server Admin and connect to the server.
2 Click the triangle at the left of the server.
The list of services appears.
3 From the expanded Servers list, select Web.
4 Click Settings, then click General.
5 In the “Persistent connection timeout” eld, specify the amount of time that can pass
between requests before the session is disconnected by the web server.
The range for connection timeout is 0 to 9,999 seconds. The default is 15 seconds.
6 Click Save.
