QUESTION Add index.php to URL

[loveelok]

@shawn_a

I tried .htaccess:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^index.php/(.*)$ $1 [R=301,L]
RewriteRule ([A-Za-z0-9-]+).html$ index.php?id=$1 [QSA,L]

In Admin CP Custom Permalink Structure::

index.php/%parent%/%slug%.html

And It working with index.php/ in url!

This Link: http://demo.com/index.php/parentdemo/demo.html

Now is working. But i don't know it optimized or not
