Is there a kind of "Socket connection pool" in nodejs?
===

In order to avoid the time spent on the creation of the sockets. 
My node server need some "long connection" to keep communicating with the server written in C which runs in the background, and all the 'http request' could share the sockets in the pool. 
I wonder if there is a kind of socket pool implementation in nodejs? (something like the database connection pool)

Any help will be appreciated !
