facebook redirect problem

hi, i pay for the solution 40 euro! is a very small problem RewriteCond %{HTTP_HOST} !^www\.example\.com$ RewriteCond %{HTTP_USER_AGENT} !(Facebot|facebookexternalhit/1.1|facebookexternalhit/1.0) [NC] RewriteRule ^(.*)$ [login to view URL]$1 [L,R=301] RewriteCond %{HTTPS} off RewriteCond %{HTTP_USER_AGENT} !(Facebot|facebookexternalhit/1.1|facebookexternalhit/1.0) [NC] RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L] this are my first lines in .htacess, so i want to exclude facebook crawler from redirect from http to https. it should only happen for google and that. but still it shows me Circular Redirect Path Circular redirect path detected (see 'Redirect Path' section for details). i used fresh JOOMLA 3.4.8 htacess and added only code above, [login to view URL] you have to imagine will replaced ;) but crawler still get s confused with the 301, because i set in https then og url to http to get the likes. server person says all is fine by them! the code is used by many developers above, so i m confused what it can be i was already thinking to make a rewritecond to an php file and this php file check s then if true or false like that: <?php $agent = $_SERVER['HTTP_USER_AGENT']; $agent = trim($agent); $agent = strtolower($agent); if ( strpos($agent,'facebookexternalhit/1.1')===0 || strpos($agent,'facebookexternalhit/1.0')===0 ){ return false; }else{ return true; } ?> BECAUSE !! php detects the crawler with that code, i checked already! but it will overwritten from htacess. i have no idea how to connect that php file with htacess without making an error. plz only apply if you are expert! this is job above!
