The “Visitor’s URL (regexp)” condition allows you to create "OR" conditions for your rules.
Simply list your URL strings and separate them with a vertical bar. The vertical bar equals “or”in this case.
In the below example, we want our rule to trigger for visitors on the giosg.com/pricing, giosg.com/products and giosg.com/our-services pages.
Our rule condition is When Visitor’s url (regexp) matches: pricing|products|our-services
When using Regexp conditions, it often is a good idea to escape possible special characters (e.g. ? , =, / ), as some of them may have a special meaning in regexps. You can escape characters by adding a backslash (\) in front of special characters.
