My server got a lot of requests like this one: "GET /lib/exe/indexer.php?id=infos&1397729200 HTTP/1.1" - sender is probably a bot, that doesn't request robots.txt.
Interestingly the server responds to all requests of that type with a 1 pixel gif. The only application on that server is DW and DW's access.log doesn't contain entries for these requests.
What is going on?
