Parent proxy only without icp query?

Hello,

I've installed a squid 2.1(patch2) to a machine.
This machine uses a parent in the following way:

                 cache_peer cache.iif.hu parent 3128 3130

If i set this, my squid always go direct, never asks my parent.
I can do the following:

              cache_peer cache.iif.hu parent 3128 3130 no-query

Then it uses the parent, but only that, and the fetched object not stored
locally. Due to the limited bandwith (64kbps) it is very bad.

My question is simple (for you, not me :):
how can i do this:
 - store all files fetched direct or from the parent locally and if a
   request made for them, provide them to the clients from the disk
 - only go direct if the parent is dead
 - if the parent is up use that (but not the above proxy-only mode:(

Is it possible that the parent does not capable to handle icp requests
made by my proxy?
If is it the problem, how can i test if a parent has that capabilities?

Thanks a lot!
