URL Rewriting - Redirect With No File Extension
Try this rule to redirect requests for .php files:
RewriteCond %{THE_REQUEST} ^GET\ /(([^/?]*/)*[^/?]+)\.phpRewriteRule ^.+\.php$ /%1 [L,R=301]
Could you just change your last RewriteRule to do this?
RewriteRule ^(.*)$ $1.php [L,R=301]That will redirect "myfile" to "myfile.php".
Also, you can adjust for this inside of Google Analytics using rules as well. Although that probably isn't an ideal solution.
ETA: If you want myfile.php to redirect to myfile, try this for your last rule instead:
RewriteRule ^(.+)\.php$ $1 [L,R=301]
You could just put in your pages a
<link rel="canonical" href="..." />
