.htaccess redirect help

Question

I'm a complete newbie to .htaccess. I've been looking around trying to figure this out.

I'm trying to figure how to do the following:

• 1 web server hosting account
• 2 different website, call them abc.com and def.com
• I want www.abc.com to continue to point to the webroot/Default.aspx. But I want www.def.com to point to www.abc.com/def/Default.aspx while www.def.com still shows up in the address bar.

The admin guy for the server farm I use stated I need to use an .htaccess file. I've been googling around trying to figure this out but only examples I find will redirect every website hit to a server to the subdirectory. I only want www.def.com calls to redirect to the subdirectory.

Answer 1

<Files .htaccess>
order allow,deny
deny from all
</Files>
RewriteCond %{REQUEST_URI} !^/def.com
RewriteCond %{HTTP_HOST} ^(www\.)?def\.
RewriteRule ^(.*)$ foldername/$1 [L]
