I'm having issues with .htaccess RewriteRule. all I'm trying to do is rewrite this url - www.example.com/public/?q=admin to - www.example.com/public/admin

but now when I go to this url www.example.com/public/admin it says not found.

but this url is working ww.example.com/public/?q=admin

here is my .htaccess code

Options All -Indexes

<FilesMatch "(config|.+\.html)\.php">
    deny from all
</FilesMatch>

<IfModule mod_rewrite.c>
    RewriteEngine on

    RewriteCond %{REQUEST_URI} !\.(bmp|cgi|css|flv|gif|ico|jpe?g|js|png|swf|xml)$
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d

Answer 1

Ok, so after your update, try this :

RewriteBase /comingsoon/public
RewriteRule ^(.*)$ /?q=$1 [L,QSA]

Answer 2

You can use this rule in your .htaccess for your required url.

RewriteRule ^public/(.*)$ public?q=$1 [L,QSA]

UPDATE 1:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^subdomain.domain.com
RewriteRule ^public/(.*)$ http://subdomain.domain.com/comingsoon/public?q=$1 [L,NC,QSA]
