suffix

The suffix expression evaluates true if the file suffix matches the second argument. This matches files name foo.php and foo.PHP but not foophp:

["suffix", "php"]

Suffix expression matches are case insensitive.

suffix-set

Since 5.0

You may specify multiple suffixes to match against by setting the second argument to an array:

["suffix", ["php", "css", "html"]]

This second form can be accelerated and is preferred over an anyof construction. In the following example the two terms are functionally equivalent but the set form has a more efficient and thus faster runtime:

["anyof", ["suffix", "php"], ["suffix", "html"]]

["suffix", ["php", "html"]]

The capability name associated with this enhanced functionality is suffix-set.
