One way to try to figure out the language of an individual person visiting your site is to look at the $ENV{'REMOTE_HOST'} variable, which (sometimes) offers the visitor's dialup location.
For example, if you see that the visitor is using a .de dialup, chances are that person may speak German.
Because of the possible performance issues with resolving ips each time a call to your server is made, your server admin may have turned off the $ENV{'REMOTE_HOST'} variable. To get around this, you can use the following code to get the remote host info anyway:
<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>
if ($ENV{'REMOTE_ADDR'} =~ /(\d+)\.(\d+)\.(\d+)\.(\d+)/){
$Address = pack('C4',$1,$2,$3,$4);
$DNS_Address = (gethostbyaddr($Address,2))[0];
$ENV{'REMOTE_HOST'} = $DNS_Address if $DNS_Address;
}
$ENV{'REMOTE_HOST'} =~ tr/[A-Z]/[a-z]/;
</pre><HR></BLOCKQUOTE>
Good luck!
