I'm rewritting my .htaccess file, and have gotten stuck. Anyone out there willing to look at it, and tell me what I messed up?

It traps error docs and sends the surfer to another page
It blocks hotlinking of images
It stops index browsing
It traps users from countires that I don't want to do business with

but it gives me a 500 internal server error!!@!!

here it is:

What does your error_log say the error was?

Added later: (oops! I looked again and I can see the errors....)

All of those country extension regexps start with ^*. and they shouldn't. :)

Try something like...

^.*\.at

I've been working with this for about an hour now simply for the sake of learning something new (as well as trying to help the guy out).

My question is, what would be the functional difference between your example:
^.*\.at
and what I came up with:
\.at$ ?

Is there any benefit of using one over the other?

Thanks,

^.*\.at will match example.at, but also matches foo.at.example.com, so it might not what you want.

OK, here's what I came up with. It worked great on my server (except for the no hotlinking section, which I didn't mess with), but I promise you nothing, as regular expressions and mod_rewrite were completely uncharted territory for me up until a couple of hours ago.

Troubleshooting the file was simply a matter of looking at my error and access logs and then fixing what they pointed to. Here are a couple of the sites I used as reference while sorting this out:

http://www.phpbuilder.com/columns/dario19990616.php3
http://httpd.apache.org/docs/mod/mod_rewrite.html
http://www.fantomaster.com/faarticles/modrewrite01.txt
http://www.fantomaster.com/faarticles/modrewrite02.txt
http://www.fantomaster.com/faarticles/modrewrite03.txt
http://www.fantomaster.com/faarticles/modrewrite04.txt

Anyway, try this:

# -----begin-----

# this first directive is kind of a quick-and-dirty way of turning on
# HostnameLookups, which you need in order for %{REMOTE_HOST} to
# return a host name rather than an IP. many servers do not allow
# you to turn hostnamelookups on through your .htaccess file, and
# this method is easier than modifying the domain's httpd.conf file.
# Alternately, you can turn on HostnameLookups server-wide through
# your httpd.conf file(s), but this method will give you less of
# a hit on server resources by confining lookups to this one domain
# The "order allow,deny" method may not be too graceful, but it works.

# HostNameLookups on

order allow,deny
allow from all
deny from lll.zzz

Got it - thanks :)

Thanks everyone. It's funny, I ended up on some of those pages referenced previously.

Everything works perfectly now.

If anyone wants a copy of the completed .htaccess file (works like a charge on my server), just PM me.
