ip address redirect based on countries

Question

Not sure if this can be done.
But I need a way to redirect visitors based on their country IP address.

Before anyone mentions it,
yes I know about Geoip , but my host does not have it, and i do not have shell access.
So Im looking for another option.

Here is the problem,
My website is generally for personal use, and I am being bombarded by spammers and unwanted crawlers plus
people looking for files i do not even have.these are from visitors all over the globe.
so i need a way to do this efficiently.

Right now im just using a messy way with regex to redirect a few of them.
like this.

#china ips-
#
RewriteEngine on
RewriteCond %{REMOTE_ADDR} ^(49\.(4|51|52|64|239)|54\.222) [OR]
RewriteCond %{REMOTE_ADDR} ^(91\.234|134\.196|159\.226|161\.207|166\.111) [OR]
RewriteCond %{REMOTE_ADDR} ^(168\.160|192\.(124|188)|193\.0)
RewriteRule !^folder/country\.html http://www.website.com/folder/country.html [L,NC,R]

While this works, it only redirects the listed regex ip addresses to a page i select.
It is good for maybe 20+ ip addresses, but if you have more than 1000+ ip addresses you need to redirect,
(which i do) your htaccess file tends to get very very big and cluttered up.

I would rather have the ip addresses in a text file, and have htaccess look for it in the cn.txt ,
or china.txt then somehow redirect any ip addresses it finds in that txt file to
http://www.website.com/folder/country.html
I know if my host had geoip it would probably make this alot easier.

I forgot to mention, my website is about 85% html, while i do have a forum gallery and faq that are php,
i generally use mostly html code. thanks

You would need to add the following PHP script to all your PHP scripts that a visitor can open. Many PHP applications have a bootstrap script where you can put this code. However, if it is not your case then htaccess is a better choice.

index.php script:

<?php
// Get user's IP address
$remoteAddr = $_SERVER['REMOTE_ADDR'];
// Load a list of regular expressions that redirect the user to 'http://www.website.com/folder/country.html'
$regexes = explode("\n", file_get_contents(dirname(__FILE__) . "/cn.txt"));

foreach ($regexes as $regex) {

    if (preg_match('/^' . $regex . '$/', $remoteAddr)) {             
         header("Location: http://www.website.com/folder/country.html");
         exit;
    }
}

Contents of cn.txt:

49\.(4|51|52|64|239)|54\.222
91\.234|134\.196|159\.226|161\.207|166\.111
and so on

Note: You can also generate your htaccess by a script (in a language of your choice). I mean you can have a list of regular expressions and generate your htaccess from that list every time you modify the list.
