SQL Netstat question
 

I just randomly did a netstat on my windows machine which hosts a site and noticed that there are hundreds of connections sitting open:

TCP server217:2469 server217:3306 TIME_WAIT
TCP server217:2470 server217:3306 TIME_WAIT
TCP server217:2471 server217:3306 TIME_WAIT
TCP server217:2472 server217:3306 TIME_WAIT
TCP server217:2473 server217:3306 TIME_WAIT
TCP server217:2474 server217:3306 TIME_WAIT
TCP server217:2475 server217:3306 TIME_WAIT
TCP server217:2476 server217:3306 TIME_WAIT
TCP server217:2479 server217:3306 TIME_WAIT
TCP server217:2480 server217:3306 TIME_WAIT
TCP server217:2482 server217:3306 TIME_WAIT
TCP server217:2483 server217:3306 TIME_WAIT
TCP server217:2485 server217:3306 TIME_WAIT
TCP server217:2489 server217:3306 TIME_WAIT
TCP server217:2490 server217:3306 TIME_WAIT
TCP server217:2494 server217:3306 TIME_WAIT
TCP server217:2495 server217:3306 TIME_WAIT

Shouldn't the connection from PHP to SQL be over a single pipe?

Thanks.
