Enter **RESPONSE\_Location** for the "**Variable name**" and "__^http://[^/]+/(.\*)__" for the "**Pattern**". This configures the rule to operate on the response HTTP header "Location" and match its value against a regex pattern that stores the URL path into a back-reference. 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. Also, the parenthesis within the pattern captures the part of the matched URL string, so that it can be reused when constructing the replacement URL. -11.
