Error log customization

[turnerb]

I have a classifieds type website, each of the ads on this website are removed on a very regular basis (sold, too old ...etc). When these ads are removed, some users might have them bookmarked - when returning to the bookmark after they're removed leaves a "File Not Found" entry in my cpanel error log. Would it be possible to do the following :

Each of the "File Not Found" entries are triggered by a file not being in the "/home/userexample/public_html/classifieds/messages" directory. Can I prevent THAT specific directory from having any affect on my log ?

I'm on a managed dedicated server, root access to change config files is not a problem.

Thanks in advance !

Anyone ? Please ?
