ConnectionPool

#include <icy/http/server.h>

LIFO connection pool for reusing ServerConnection objects. Avoids per-request heap allocation by resetting and reusing connections instead of destroying and recreating them.

Public Methods

Return	Name	Description
`ServerConnection::Ptr`	`acquire` `inline`	Takes a connection from the pool for reuse.
`bool`	`release` `inline`	Returns a connection to the pool after use.
`void`	`setMaxSize` `inline`	Sets the maximum number of connections the pool will hold.
`size_t`	`size` `const` `inline`	Returns the current number of connections held in the pool.
