Request exceeded the limit of 10 internal redirects due to probable configuration error

I'm getting the following error in my CakePHP application:

Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace., referer: http://projectname.dev/

My .htaccess in the root folder, looks like this:

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

and in the app folder:

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

and in the webroot folder:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /projectname
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

I was following this tutorial:

http://book.cakephp.org/2.0/en/getting-started.html

I just found a solution to the problem here:

https://willcodeforcoffee.com/cakephp/2007/01/31/cakephp-error-500-too-many-redirects.html

The .htaccess file in webroot should look like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

instead of this:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /projectname
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

//Just add 

RewriteBase /
//after 
RewriteEngine On

//and you are done....

//so it should be 

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]

i solved this by http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/</strike> just uncomment or add this:

RewriteBase /
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

This error occurred to me when I was debugging the PHP header() function:

header('Location: /aaa/bbb/ccc'); // error

If I use a relative path it works:

header('Location: aaa/bbb/ccc'); // success, but not what I wanted

However when I use an absolute path like /aaa/bbb/ccc, it gives the exact error:

> Request exceeded the limit of 10 internal redirects due to probable > configuration error. Use 'LimitInternalRecursion' to increase the > limit if necessary. Use 'LogLevel debug' to get a backtrace.

It appears the header function redirects internally without going HTTP at all which is weird. After some tests and trials, I found the solution of adding exit after header():

header('Location: /aaa/bbb/ccc');
exit;

And it works properly.

Following the cakePHP official documentation, the .htaccess should be like this:

https://book.cakephp.org/2/en/installation/url-rewriting.html

   <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteRule ^(.*)$ index.php [QSA,L]
    </IfModule>

simply removing the rewrite base in the internal .htaccess file fixed mine . like a had an htaccess file in my root directory simply linking to an index page in the public directory which is in my root folder then i had another htaccess file rewriting each request to the index page in that same public folder , and removing the RewriteBase fixe mine . as shown below

this is the first .htaccess file in the root directory
