Need help with ASA config to set up proxy on DMZ

Question

Hello guys,
I have a problem, I´m trying to configure an ASA as shown in the attached scenario.
I need that all inside users to go to the proxy server on DMZ and from there they will go out to the internet.
Right now i have:
INSIDE INTERFACE
Access-list inside permit ip 10.1.1.0 255.255.255.0 host 11.1.1.6
DMZ INTERFACE
Access-list dmz permit ip host 11.1.1.6 any
OUTSIDE INTERFACE
Access-list outside permit ip any host <proxy server public ip>
REGARDING NAT I HAVE THE FOLLOWING:
Static (dmz,outside) <proxy server public> 11.1.1.6 netmask 255.255.255.255
My question would be if it would work with this configuration? Do i need to apply Nat on my inside hosts?  Would all my inside hosts when reached the ASA will be send to the proxy and then through the proxy it will send them back to the ASA and then to the internet??
Thanks,
Tony

Hello Jennifer,
Thanks for your response. So basically i will need to add a static to allow trafic from inside to dmz without being natted. I don't know what proxy server it will be, the server would be managed by another party, but in my inside hosts i will need to set all the parameters to point to the proxy, once this done trafic will go out through the proxy server to the dmz interface of the ASA and then to the outside world, is that correct?
Do you think this configuration would work???
Outside = security 0
Inside = security 100
DMZ = security 50
static (dmz,outside) 11.1.1.6 netmask 255.255.255.255
static (inside,dmz) 10.1.1.0 10.1.1.0 netmask 255.255.255.0
access-list inside permit tcp 10.1.1.0 255.255.255.0 any
access-list dmz permit ip host 11.1.1.6 any
access-group inside in interface inside
access-group dmz in interface dmz
Basically with this configuration my web request will go to the proxy on the DMZ and then from there it will go out to the internet??
Thanks
