How to disable Keep-Alive per Directory

Question

Is it possible to disable Keep-Alive on a directory basis?

For example, I have an API that runs on something like domain.com/api/

It'd be nice if KeepAlive was not used on any requests in the /api/ directory.

Update/Solution:

SetEnvIf Request_URI /api/ nokeepalive
