Can't figure out a htaccess rule

Question

I have this in my htaccess but can't figure out what its for. Because of the nature of rule, searching doesn't help either.

RewriteCond %{REQUEST_URI} !(/$|\.)
RewriteRule (.*) %{REQUEST_URI}/ [R=301]

Can anyone please explain what its for?

Answer 1

This means :

• If it's not true (!) that either ((|)):

  • the URI ends with a slash (/$), or
  • the URI contains a point (\.),

• Then append a slash to the URI (%{REQUEST_URI}/), and

• Return the new URI to the client's browser with return code 301 ([R=301]), which means permanent redirect to the new URI, and which also tells the browser to display the new URI in the address bar.
