Redirect from https to http except One folder

Sometimes we need to redirect all URL from https to http except one URL,In that case we just have to add below line above the redirection code in .htaccess file:

RewriteRule  ^foldername/  -  [L]

Now all the url except the foldername will be redirected from https to http:

RewriteRule ^foldername/ - [L]
RewriteCond %{SERVER_PORT} ^443$
RewriteRule ^(.*)$ http://www.cpanelplesk.com/$1 [R=301,L]

Done.
