I've found some messages like this one, in my nginx error.log.

open() "[my-domain]/**iptac-***[a long long string]*/http:/[my-domain]/"
failed (2: No such file or directory), client: , server: , request:
"GET **/iptac-***[a long long string]*

I've changed some parts of the message for privacy, but the "long long string" seems to be something like an encrypted string.

Google doesn't know anything about iptac-, but I've found a website that reports a very similar URL (please, click on the follow link to see the reported URL with that iptac).


What is this?

IPTAC usually relate to a Cisco Web Security Appliance. Can be like a cookie insert for a url redirect.
