i think the best way is to remove the .htaccess from the public directory (Zend Framework Directory structure) , and put it with the following content into your "root" directory :
RewriteEngineOn
RewriteRule^.htaccess$ -[F]RewriteCond%{REQUEST_URI}=""RewriteRule^.*$ /public/index.php [NC,L]
RewriteCond%{REQUEST_URI}!^/public/.$ RewriteRule^(.)$ /public/$1 RewriteCond%{REQUEST_FILENAME}-f RewriteRule^.*$ -[NC,L]
RewriteRule^public/.*$ /public/index.php [NC,L]
