.htaccess related codeigniter. why error 404 page not found?



befor I add my website to any hosting I used xampp, so I caller url like :

http://localhost/myCI/folderAdmin/controller/

in my xampp I use this htaccess file:

Options -Indexes

<IfModule mod_rewrite.c>

RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_URI} ^system.*

RewriteRule ^(.*)$ index.php?/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ myCIname/index.php?/$1 [L]

</IfModule>

<IfModule !mod_rewrite.c>

ErrorDocument 404 /index.php

</IfModule>

all feature it's work well. but in hosting any error in one page, that

give me '404 page not found'. I called url :

http://www.myurl.com/folderAdmin/controller/

with the htaccess file:

Options -Indexes

<IfModule mod_rewrite.c>

RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_URI} ^system.*

RewriteRule ^(.*)$ index.php?/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php?/$1 [L]

</IfModule>

<IfModule !mod_rewrite.c>

ErrorDocument 404 /index.php

</IfModule>

what's wrong with that? please for help.
