Web cache policy commands

aging-time

Syntax

aging-time time-value

Parameters

time-value: Specifies the aging time in the range of 1 to 1440 minutes.

Usage guidelines

A cached file is automatically deleted when its aging timer expires.

The aging timer of a cached file is not restarted when the device receives the same HTTP requests as the first HTTP request that triggers the generation of the file.

If you modify the aging time, the new setting takes effect only on newly generated files and does not affect existing files.

Examples

# Set the aging time of cached files to 180 minutes in HTTP Web cache policy cp1.

<Sysname> system-view

[Sysname] cache-policy cp1 type http

[Sysname-cp-http-cp1] default-aging-time 180
