1. Symptom:

I found lots of requests for the same resource on Apache logs, like this:

It's not a problem for your web server. It's the client who sends the same request multiple times. Maybe an old IE, or any browser/application that does not use cache.

Those are requests for an image associated with the dhtmlxTree script (cf.), which you're presumably using somewhere on your site. The response code seems to be 200, so no problem.

What's the confusion?
