What's the best way to avoid/prevent this from happening?...
Since the IP is part of a Turkish /24 network, odds are it's a hack
attempt. If you don't care about servicing Turkey, you could block that
IP space in your firewall. Pertinent information:
inetnum: 185.4.227.0 - 185.4.227.255
netname: SAYFANET
descr: Istanbul DC Customer
country: TR
admin-c: KSM20-RIPE
tech-c: KSM20-RIPE
status: ASSIGNED PA
mnt-by: ER101-MNT
source: RIPE # Filtered
("whois 185.4.227.194" will give you the gory details), so add that /24
to your filter list. In the old days:
iptables -I INPUT [some-rulenumber] -s 185.4.227.0/24 -j DROP
It's difficult to weed out traffic selectively unless you have the
ability to do a deep packet inspection and look at the actual request.
Generally that equipment costs a good deal of $$$$.

It certainly looks that way. I see several of those kinds of GETs a
day on our web servers. Not from that particular domain, but similar
types of GETs.
A quick google points to similar GET requests to that domain as far
back as 2011, and the domain itself isn't live, just a placeholder for
parked domain.
