Multiple RewriteCond, How Would This Code Work?

Question

I have this in my *.conf file ( I got this from someone else, not sure whether there is a bug or not), which I don't quite understand:

  RewriteEngine on
  RewriteBase /
  RewriteCond %{HTTP_HOST} mycompany.com
  RewriteRule ^$  http://mycompany.com/login   [L]
  # we check if the .html version is here (caching)
   RewriteRule ^$ index.html [QSA]
   RewriteRule ^([^.]+)$ $1.html [QSA]
   RewriteCond %{REQUEST_FILENAME} !-f

   # no, so we redirect to our front web controller
   RewriteRule ^(.*)$ index.php [QSA,L]

I roughly understand what it does; first it checks whether the incoming request is mycompany.com, if yes, then redirects to http://mycompany.com/login.

Then, what is the next condition to check? The fact that there is this

RewriteRule ^$ index.html [QSA]
RewriteRule ^([^.]+)$ $1.html [QSA]

come before the RewriteRule ^$ http://mycompany.com/login [L] is confusing me.

Is there anyway to rewrite the above script in a RewriteCond, RewriteRule, RewriteCond, RewriteRule format?

Answer 1

You have a ambiguous indentation of your configuration file.

Maybe the following is a bit clearer:

RewriteEngine on
RewriteBase /

# If the requested hostname is mycompany
# and no path segment was given,
# redirect to /login
RewriteCond %{HTTP_HOST} mycompany.com
RewriteRule ^$  http://mycompany.com/login   [L]

# Add .html extension to any requested filename.
RewriteRule ^([^.]+)$ $1.html [QSA]

# Check if requested filename (now with .html
# extension) exists,
# otherwise redirect to front controller
RewriteCond %{REQUEST_FILENAME} !-f  
RewriteRule ^(.*)$ index.php [QSA,L]

I removed

RewriteRule ^$ index.html [QSA]

because this could more easily be done with the DirectoryIndex directive.
