I’m getting lots of requests on my sites for urls that include “RK=0” as the end of the URL. I block all of those requests. Here are a couple links I’ve found that describe and discuss what those odd “RK=0” requests are:
- Xenforo: Server Logs with RK=0/RS=2 …. I now know what these are
- The Blackboard: IT Q: “.. //RK=0/RS=foo-” in URI
