Apache find the sender of get request

Question

What's the easiest way to find the sender of a get request from apache? I keep seeing error logs that imply some page/application is sending a get request for a favicon file, which is nonexistent. I grep'd my entire webhost directory but not a single file in there is referencing this nonexistent favicon file.

Is there a way to find out exactly what or who is sending the get request for this file?

Apache 2 on CentOs.

Answer 1

Nevermind, most modern browsers request favicon files regardless.
