I have this url structure: proyectos.example.com/ci-doctrine/index.php proyectos.example.com/ci-doctrine/index.php/welcome proyectos.example.com/ci-doctrine/index.php/blog proyectos.example.com/ci-doctrine/admin.php proyectos.example.com/ci-doctrine/admin.php/welcome proyectos.example.com/ci-doctrine/admin.php/dashboard For index.php urls,

I have this url structure:

proyectos.example.com/ci-doctrine/index.php
proyectos.example.com/ci-doctrine/index.php/welcome
proyectos.example.com/ci-doctrine/index.php/blog
proyectos.example.com/ci-doctrine/admin.php
proyectos.example.com/ci-doctrine/admin.php/welcome
proyectos.example.com/ci-doctrine/admin.php/dashboard

For index.php urls, I would like to keep this format:

proyectos.example.com/ci-doctrine/    //default index view
proyectos.example.com/ci-doctrine/welcome
proyectos.example.com/ci-doctrine/blog

So, my .htaccess looks like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>

The .htaccess code above works fine. The problem resides for admin.php urls, because I want the urls format like (keeping the ‘admin’ word):

proyectos.example.com/ci-doctrine/admin
proyectos.example.com/ci-doctrine/admin/dashboard
proyectos.example.com/ci-doctrine/admin/welcome

Then, I have editted my htaccess like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  #RewriteCond %{REQUEST_URI} ^admin/(.*)$ [NC]
  RewriteRule ^admin/(.*)$ /admin.php/$1 [L]

  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>

But when I browse proyectos.example.com/ci-doctrine/admin I get a 500 error, so I suppose that my rule for admin file is not working good enought.

Logs

I have reviewed the error_log, and each time I try to acesss proyectos.example.com/ci-doctrine/admin it prints a message:

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.

Followed by a list of redirections:

Directory structure

For troubleshooting porpuses, below you can find my dir structure

public_html/
    .htaccess/
    index.php
    proyectos/
        ci-doctrine/
            .htaccess
            index.php
            admin.php

Document root .htaccess

In the root, I have another installation of my application like in the subdomain proyectos.example.com/ci-doctrine does, for this reason I am applying the same rule for index.php for urls. 

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

UPDATE > working code

Well, with the help of @anubhava I got this work:

Document root .htaccess:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /

  RewriteCond %{HTTP_HOST} ^(www\.)?example\.com [NC]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>

Subdomain .htaccess:

# If the user types "index.php" or "admin.php".
RewriteCond $1 !^(index\.php|admin\.php|images|robots\.txt)

# If the user types just "admin".
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin$ admin\.php [L,QSA]

# If the user enter in any admin section, like "admin/section".
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin\/(.*)$ admin\.php/$1 [L,QSA]

# If the user types any site section, like "site/section".
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index\.php/$1 [L,QSA]

    Actually the problem is one extra (and incorrect) RewriteCond in your first rule. Here is the modified and correct code that should work for you:

    RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin/(.*)$ /admin.php/$1 [L,NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]

    EDIT: Your $DOCUMENT_ROOT/.htaccess should be modified like this:

    <IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /

  RewriteCond %{HTTP_HOST} ^(www\.)?rootdomain\.com [NC]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
