.htaccess RewriteEngine

[sanson]

Dear All,
Please help me to fix this I am new to RewriteEngine Rules

I have a WHOIS Lookup Script on my website
The URL is http://whois.domain.com/whois.php?domain=example.com

Now I need to achieve this http://whois.domain.com/example.com

So I wrote

RewriteEngine On
RewriteRule ^([\w\-]*)$ whois.php?domain=$1

In the above code I am not getting the domain extension passed, I know the code is wrong, but dont know where.

Please HELP.

You forgot to match the point. Plus "\w" will not match numbers and other weird characters.
Try this instead (not tested):

RewriteRule ^([a-z0-9\-\._]+\.[a-z]+)$ whois.php?domain=$1

When I use
RewriteRule ^([a-z0-9\-\._]+\.[a-z]+)$ whois.php?domain=$1
I get an ERROR

Sorry, that tld is not supported.

------------------------------------------------------------

But, If I delete the .htaccess and use the below URL it works fine

http://whois.domain.com/whois.php?domain=example.com

Hmm I don't really see anything wrong on first sight...

Could you post the TLD that gave the error?

I just tried with demo.com

Please Help When I use

RewriteRule ^([a-z0-9\-\._]+\.[a-z]+)$ whois.php?domain=$1

I get an ERROR

Sorry, that tld is not supported.
