Zypper No proxy use Axel?

I just installed opensuse for the first time and found that can’t download anything via zypper.I’m behind institute firewall,hence use proxy for connecting to the net.The yast install is working fine but zypper is not
I looked at some posts and could gather that zypper uses aria2.c or curl for download.So i guess i’ll have to set up proxy there.My question is that can i do something so that zypper downloads using axel,which is much much faster than others,but since it fails sometimes,maybe i revert to curl or aria2 ?
I had done this previously in my other linux distros where i’d use axel with winetricks instead of wget and similarly in playonlinux.if it could be done on zypper it will save a lot of time in emerging world for me.
