This is a server-side Condition which compares the URL of the visitor’s previous page against a URL or partial URL specified when configuring the Condition. This Condition makes no distinction between internal and external URLs when performing any comparisons.
The following configuration options are available for this Condition:
Operator: This is used to specify the type of comparison to perform. You can check whether or not the URL of the previous page contains a specified value, or whether or not that URL is within a specified list of URLs. You can also choose to perform a regular expression match by selecting Matches regular expression from the dropdown.
Value: This is used to specify the value used to perform the comparison.
Regular Expression: If you select Matches regular expression from the Operator dropdown, this text box is used to enter the regular expression you wish to use.
Test Regular Expression: This button appears when you select Matches regular expression from the Operator dropdown. It is used to provide a sample of text against which to test the Regular Expression specified for this Condition. Type in some sample text and press the Test button. A tick or cross is displayed to indicate whether the Regular Expression is valid when run against the sample text provided.
Case Sensitive: This is used to specify whether or not the Condition uses case sensitive matching. Checking the box instructs the Condition to use case sensitive matching. This option is not available if you selected Matches regular expression from the Operator dropdown.
Trim Whitespace: This is used to specify whether or not to trim leading or trailing whitespace from the value used for the comparison. Checking the box means that leading or trailing whitespace shall be removed.
