redirect external referrer (htaccess)

redirect external referrer

[tuuni]

How to redirect all traffic (to my site's certain htm page.. example: sub.site.com/folder/file.htm) who are not coming directly to my site.

Something like this but this is not correct..

RewriteCond %{HTTP_REFERER} !^http://sub.example.com
RewriteRule !^$ http://sub.example.com/folder/file.htm [R=302,L]

How can it be done?

You did not say how you tested, what results you got, and how those results differed from what you expected, so we can only guess why you think your code is incorrect. I'd suggest:

RewriteCond %{HTTP_REFERER} .
RewriteCond %{HTTP_REFERER} !^http://sub\.example\.com
RewriteRule ^(([^.]+\.)+(s?html?|php[0-9]{0,2}))?$ http://sub.example.com/folder/file.htm [R=302,L]

"IF the referer is sub.example.com, sub.example.com., sub.example.com:80, sub.example.com,:80, or blank (these are all perfectly-valid HTTP Referrer values),
AND if the request is for a .shtml, .shtm, .html, .htm, .php, or .php5 'page' or a blank URL-path indicating your 'home page',
THEN redirect to sub.example.com/folder/file.htm"
