Operations That Evaluate Cache-Control Headers

NAME(integer)

Returns as a text value the name of the Cache-Control 
header that corresponds to the nth component in a 
name-value list, as specified by integer.

The index of the name-value component is 0-based. If 
the index that is specified by the integer argument is 
greater than the number of components in the list, a 
zero-length text object is returned.

Following is an example:

http.req.cache_control.name(3).

contains("some_text")
