day=

Tests if the day of the month is in the specified range or an exact match. The ProxySG appliance’s 
configured date and time zone are used to determine the current day of the month. To specify the UTC 
time zone, use the form 

day.utc=

. Note that the numeric pattern used to test the day condition can 

contain no whitespace.

day[.utc]={[first_day]..[last_day]|exact_day}

where:

•

—An integer from 1 to 31, indicating the first day of the month that will test true. If left 

blank, day 1 is assumed.

•

—An integer from 1 to 31, indicating the last day of the month that will test true. If left 

blank, day 31 is assumed.

•

—An integer from 1 to 31, indicating the day of the month that will test true.

To test against an inverted range, such as days early and late in the month, the following 
shorthand expression is available. While 

day=(..5|25..)

 specifies the first 5 days of the 

month and last few days of the month, the policy language also recognizes 

day=25..5

 as the 

same.

Use in all layers.

Using time-related conditions to control caching behavior in a 

<Cache>

 layer may cause thrashing 

of the cached objects.
