[users@httpd] Limiting users possibilities in .htaccess files

[Markus Mayer <my...@gmx.at>]

Hi all,

I have some users on my server who insist on writing .htaccess files and 
defining proxies in them.  This is something I don't like or want, they also 
run against our firewall which causes some security related messages to be 
generated.  I have tried different restrictions with AllowOverride however 
all I did was kill off other important functionality.  Is there some way I 
can restrict users so that when they define a proxy in a .htaccess file the 
server returns some kind of error to the user?  In otherwords, when a user 
does something like 
RewriteRule ^something/(.*)$ http://someserver.com/something/$1 [L,P]
I want an error message to be returned, something like the standard "Internal 
Server Error" message is perfectly ok.

I will appreciate all help!
Markus

You need to remove FileInfo from your AllowOverrides or remove
mod_proxy or mod_rewrite from your loaded modules.  There is no other
way in apache.  (The social solution is to do automated monitoring of
.htaccess files with a script and kill accounts that misuse them.)
