The Expiration attribute only overrides the default attribute value; it is ignored if a specific catalog::Expiration value applies to the request.

Data

<expression>
Optional.
<substitution>
Optional.
<addressfilter>

Notes

If both <expression> and <substitution> are specified, and captured substrings are not used, the first matched sub-string is replaced with <substitution> .
If <expression> is not specified, any path will match and <substitution> is appended to the end of the path.
If <substitution> is not specified, the matched substring is removed.
The <addressfilter> is applied only when a match occurs, and before query rules are applied.
