 9. Expand the "**Conditions**" group box, select "**Add**" and enter **{ORIGINAL\_HOST}** as a condition input and "**.+**" as a condition pattern. This condition checks if the temporary server variable ORIGINAL\_HOST exists and has a non-empty value.
 10. Select **Add** one more time and add another condition. Set the condition input to **{URL}** and the pattern to "__^/(webmail|payroll)/.\*__". This regular expression is used to match the URL paths that start with either /webmail or /payroll.
