The Bakery Everything CakePHP

This worked:
http://mysite.com/sub/

This did not:
http://mysite.com/sub

Usually Apache figures out that "sub" is a directory and will redirect to the slashed location for you. However, CakePHP's default mod_rewrite rules play havoc with this and the result was a 400 Bad Request error. The solution is relatively simple, but was not intuitively easy to figure out.

CakePHP ships with this .htaccess file in the base CakePHP directory:

Download code
<IfModule mod_rewrite.c>
  RewriteEngine  on
  RewriteRule ^$  app/webroot/     [L]
  RewriteRule (.*) app/webroot/$1  [L]
</IfModule>


In my attempts to solve this problem, I had tried several rewrite rules and redirects from within this file and from within my website's root web directory (one above the CakePHP directory), but only the following worked for me:

1.) Put this in your website root directory (where "sub" is your CakePHP directory):
Download code
<IfModule mod_rewrite.c>
  RewriteEngine  on
  RewriteRule ^sub$       sub/app/webroot/     [L]
  RewriteRule ^sub/(.*)$ sub/app/webroot/$1  [L]
</IfModule>


2) AND, DELETE OR RENAME your .htaccess file in the CakePHP sub directory.


Hope that helps someone.
