I have the following htaccess:
RewriteRule test2$ home.php?ID=1 [NC] [L]
RewriteRule test2/News$ news.php?ID=1 [NC] [L]
RewriteRule test2/Contact$ contact.php?ID=1 [NC] [L]
RewriteRule test2/ContactSent$ send.php?ID=1 [NC] [L]
RewriteRule test3$ home.php?ID=4 [NC] [L]
RewriteRule test3/News$ news.php?ID=4 [NC] [L]
RewriteRule test3/Contact$ contact.php?ID=4 [NC] [L]
RewriteRule test3/ContactSent$ send.php?ID=4 [NC] [L]
RewriteRule test4$ home.php?ID=5 [NC] [L]
RewriteRule test4/News$ news.php?ID=5 [NC] [L]
RewriteRule test4/Contact$ contact.php?ID=5 [NC] [L]
RewriteRule test4/ContactSent$ send.php?ID=5 [NC] [L]
Now when I send an email using the php mail() on the /ContactSent page it sends the email 3 times. How can I stop that?
