Fake requests


I have started using Apache mod_rewrite feature to make SE friendly URLs. However in the logs I can see a lot of requests for contact.php with various path like:

There is no contact.php at all on the server. There are ~3-6 such requests in every minute.
This requests worries me, but don’t know what to do against it.

Any idea?

Thanks in advance!

As long as those files don’t exist you don’t have much to worry about. They will just be from bots searching for contact forms on websites to exploit.

Just make sure if you do have a contact form you have secured it with a captcha facility.
