title: How to delete the name of the controller in the URL with CodeIgniter?
body: <p>I have urls that all contain /main/ in the url as it is my main controller.
  I'd like to get rid of it.</p>
  
  <p>I understood in the User Guide that the routing class will only re-route my URL, not hide a part of it (it is segment 1 according to their docuementation).
  Thus, I've found this:</p>
  
  <pre><code>$route['(:any)'] = "auth/$1";
  </code></pre>
  
  <p>But I have 404 errors (That's the only modification I made to routing.php)</p>
  
  <p>I believe I'll have to do it in the .htaccess, but I don't know what should be the syntaxe for that. For now, my .htaccess is this one:</p>
  
  <pre><code>&lt;IfModule mod_rewrite.c&gt;
      SetEnv MAGIC_QUOTES 0
      SetEnv PHP_VER 5
  # For security reasons, Option followsymlinks cannot be overridden.
  #   Options +FollowSymlinks -MultiViews
      Options +SymLinksIfOwnerMatch -MultiViews
      RewriteEngine On
      DirectoryIndex index.php
  
      #Removes access to the system folder by users.
      #Additionally this will allow you to create a System.php controller,
      #previously this would not have been possible.
      #'system' can be replaced if you have renamed your system folder.
      RewriteCond %{REQUEST_URI} ^system.*
      RewriteRule ^(.*)$ /index.php?/$1 [L]
  
      #When your application folder isn't in the system folder
      #This snippet prevents user access to the application folder
      #Submitted by: Fabdrol
      #Rename 'application' to your applications folder name.
      RewriteCond %{REQUEST_URI} ^application.*
      RewriteRule ^(.*)$ /index.php?/$1 [L]
  
      #Checks to see if the user is attempting to access a valid file,
      #such as an image or css document, if this isn't true it sends the
      #request to index.php
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteCond %{REQUEST_FILENAME} !-d
      RewriteCond $1 !^(index\.php|images|robots\.txt|css)
      RewriteRule ^(.*)$ index.php?/$1 [L]
  &lt;/IfModule&gt;
  
  &lt;IfModule !mod_rewrite.c&gt;
      # If we don't have mod_rewrite installed, all 404's
      # can be sent to index.php, and everything works as normal.
      # Submitted by: ElliotHaughin
  
      ErrorDocument 404 /index.php
  &lt;/IfModule&gt;
