FlashConnect's server pooling extends the concept of connection pooling.
Connection pooling enables applications to reuse a connection from a pool of connections. Once a connection is created and placed in the pool, an application can use a connection within the same pool without performing the complete connection process. Connections (when released by an application) remain available, waiting for the next occasion they are needed.
Server pooling allows the naming and grouping of one or more FlashConnect connections. Server pools can connect one or more database servers to one or more Web servers. Server pools enable the distribution of an application across several systems, and allow load balancing and tighter control of resource allocation. Setting up, configuring and using server pools are optional.
The URL specifies which system should process a request and which server pool to use.
FlashConnect assigns the connection to any database server which supports that server pool using the value assigned to the w3ServerPool variable.
