what does '.action' mean in a robots.txt file?

Question

I'm looking at a robots.txt file that includes a line Disallow: /path/p.action. I would understad if it said /path/p* as forbidding accessing any page that begins with p. But what does action refer to?

Answer 1

It asks robots not to fetch any path starting with /path/p.action.

.action usually indicates that there is Java code running on the server. See .action extension... what is it?
