Apache rewrite_rule for angularjs

I have this rule in Angularjs app. It work perfectly. But I want to understand one rule which I don't know what it does RewriteRule ^.*$ - [NC,L] #???

RewriteEngine on
RewriteBase /

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -!f 
RewriteRule ^.*$ - [NC,L] #NC none-case-sensitive, L stop when match
RewriteRule ^(.*) index.html [NC,L]

Please help me on this rule RewriteRule ^.*$ - [NC,L] I know about the [NC,L] flags but I don't get ^.*$ - especially the empty dash at the end of rule.

The syntax of the RewriteRule is:

RewriteRule Pattern Substitution [flags]

Your rule is:

RewriteRule ^.*$ - [NC,L]

  • ^.*$ is a perl compatible regular expression where

    • ^ is the start of string
    • . is any character except newline
    • * means 0 or more times
    • $ is the end of string.

  • The substiution is - which means: "no substitution should be performed (the existing path is passed through untouched). This is used when a flag needs to be applied without changing the path."

  • The flags are NC and L, which means:

    • NC: Makes the pattern comparison case-insensitive.
    • L: Stop the rewriting process immediately and don't apply any more rules. Especially note caveats for per-directory and .htaccess context (see also the END flag).

So this rule matches anything, makes no substitution, and stops the rewriting process immediately.
