Maximum HTTP inbound priority

[sallain]

Hi All@Forum :)

I'm should perform in a couple of days a pfSense installation (my real first one) : I have already played with PF2.1 => no majors troubles for install/setup/OpenVPN, etc…

But I have a question about Traffic Shaping.

Installation wil be this

INTERNET
  ||
  ||
4MB SDSL Modem/Cable
  ||
  ||
PFSense Appliance
  ||
  ||
NETWORK_SWITCHES
  ||
  ||
One Apache/IE WebServer

Very basic situation ;-)

My main deal is to give the enduser the possibility to have to HIGHER inbound HTTP/Web traffic possible (let's say 90%...) toward the Apache / IE WebServer. Because of a the traffic, I suppose I can use traffic shapper to setup incoming HTTP (TCP = 80) using 90% of the 4MB SDLS link.

Is that possible with pfSense ? If yes, how to setup ?

I will really appreciate your opinions and help, I'm afraid it could be a hard task...

Thanks a lot for help :)

Regards.
