.htaccess noob questions
My objective is this: every file sent out by the server with a .gif extension should be run through a php script first. E.g., if you request mydomain.com/example.gif, I want the server to send you script.php?url=example.gif. Simple enough?
I presume there's a way to do this using a .htaccess file. (I'm running Apache 2). I figured I'd just try it out, by inputting this script I pulled off of some website that's supposed to prevent remote image loading:
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^[url]http://booya\.no-ip\.org/[/url] [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteRule \.(jpe?g|gif|bmp|png)$ images/nohotlink.jpg [L]Here I encountered my first problem: I can't name the file .htaccess because Windows won't allow a filename to begin with a period. Does the filename have to be ".htaccess", or can it be something like "something.htaccess"?
I've tried naming it "something.htaccess" and it doesn't seem to be blocking anything.
Of course, my second question once this is working is going to be, how do I get it to do what I want it to do? If someone just wants to link me to a writeup on how this syntax works, that would be appreciated.

does your server use cpanel? if so then you can do it through there instead of doing it yourself.

Cpanel is not currently available for Windows Servers. You should be able to rename the file by doing this from the command line (DOS prompt).
ren something.htaccess ".htaccess" with the quotes around the .htaccess. You usually don't have that problem in Windows 2000/XP, mainly on Windows 9X machines.
Doing something like that will be very processor intensive on your site. Just curious what your reason is for attempting this?

Yep, I have the file renamed fine... funny, I'm running Windows 2000.
But it doesn't seem to do anything.
For the record, I'm just building the site on my Windows box. The server where it will end up will undoubtedly be running a real OS.
The php script embeds text into a gif file. Since many people don't know about gif comment fields, this should serve as a decent security mechanism to prevent people from ripping off our images.

Still no...
It looks like Apache isn't even looking at .htaccess. It's in the same directory with the image... do I need to do anything with Apache's config files?

is your mod_rewrite being loaded in your apache config?

I... have no idea what that means.
Update:
I got this to work by changing the config from "AllowOverride none" to "AllowOverride All".
I've also uncommented LoadModule rewrite_module modules/mod_rewrite.so
Now I just don't know how to get it to do what I want. Can anyone help?
I need to replace (foo).gif with secure.php?url=(foo).gif. A few issues: since there can't be slashes after the question mark in the url, I need to escape those or replace them with another character; also, it needs to only do this replacement if ".php" isn't in the url, to prevent looping.
I don't understand the syntax well enough at this point to write anything that works... so any help would be great.

Mmmkay, I got it working:
RewriteEngine onRewriteCond %{REQUEST_URI} ^(.*).gif$
ReWriteRule ^(.*)?/(.*)?$ $1~$2
ReWriteRule ^(.*).gif$ secure.php?url=$1.gif
Problem solved.
