The file contains a list of URLs specifying objects that you want to schedule for update. .sp A scheduled update performs a local HTTP \fBGET\fP on the objects at the specific time or interval. You can control the following parameters for each specified object: .INDENT 0.0 .IP \(bu 2 The URL .IP \(bu 2 URL\-specific request headers, which overrides the default .IP \(bu 2 The update time and interval .IP \(bu 2 The recursion depth .UNINDENT .sp After you modify the \fI\%update.config\fP file, run the \fBtraffic_line \-x\fP command to apply changes. When you apply changes to one node in a cluster, Traffic Server automatically applies the changes to all other nodes in the cluster. .SH SUPPORTED TAG/ATTRIBUTE PAIRS .sp Scheduled update supports the following tag/attribute pairs when performing recursive URL updates: .INDENT 0.0 .IP \(bu 2 \fB\fP .IP \(bu 2 \fB\fP .IP \(bu 2 \fB\fP .IP \(bu 2 \fB\fP .IP \(bu 2 \fB\fP .IP \(bu 2 \fB
