I dont think it exsists, because it would allow you to get sensitive data from the other users.
Free hosts uses 1 apache for sereval websites, you get a directory inside their www directory. For instance /apachedir/www/mysite/web/com/. Another user could have /apachedir/www/hissite/web/com/.
Therefore, you could get the other users log too which could contain sensitive data.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
