Create a rule for setting text as the value of a user-defined property
Monitoring
Logging 8
A rule can convert text that is the body of a web object to a list of strings and set this list as the value
of a used-defined property.
To configure this rule:
1 Go to Policy | Rule Sets.
2 From the rule sets tree, select the rule set you have created for the rule, for example, Block Unwanted
Text.
3 On the settings pane, click Add Rule. The Add Rule Window opens with the Name step selected.
4 In the Name field, type the rule name, for example, Set User-Defined.listOfWords.
5 Select Rule Criteria and under Apply this rule, select Always.
6 Select Action and from the Action list, select Continue.
7 Select Events, click Add, and select Set Property Value. The Add Set Property window opens.
8 From the list under Set this property, select the user-defined property you created, for example,
User-Defined.listOfWords.
9 Under To this value, select Property and from the list of properties, select String.ToStringList.
10 Click Parameters. The Property Parameters window opens.
11 Configure the three parameters of the String.ToStringList property as follows:
a Parameter 1: Select Property and from the list of properties, select Body.Text.
b Parameter 2: Make sure Value is selected, and in the List Delimiter field, type the character to
use as a delimiter.
c Parameter 3: Make sure Value is selected, and in the Trim Characters field, type the characters
you do not want to appear at the beginning and end of words in the string list that is the result of
the conversion.
12 Click OK to close the Property Parameters window and then again for the Add Set Property window.
13 Click Finish. The Add Rule window closes and the new rule appears on the settings pane.
After using this rule to set a particular text as the value of the User-Defined.listOfWords property, you
can use another rule to compare this text to a list of key words and eventually execute a blocking
action.
For more information about this rule, see Create a rule for blocking text with bad key words.
For more information about delimiters and trim characters and how to specify them as parameters, see
the description of the String.ToStringList property in the List of properties.
Add action settings for a key word blocking rule
When a rule blocks text containing key words, the settings of the blocking action can specify a message
to the user who requested access to this text.
To add these settings to the preconfigured settings for blocking actions:
1 Go to Policy | Settings.
2 On the Actions branch of the settings tree, select Block.
3 Click Add. The Add Settings window opens.
4 Configure the following general parameters:
• Name — For example: Bad Words Found
• Comment — [Optional] Plain-text comment on the settings
