Apache, htaccess, url rewrite

I have .htaccess file I'm using for testing, here is my file:

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%{SERVER_NAME}/?title=%1 [L]

I'm using Apache/2.4.10 (Win32) from ApacheLounge

I have the following domain and sub domain:

• example.com
• m.example.com

Both point to the same ip address, now as I expected from the above .htaccess:

if I access example.com/Article-Name/ the redirection to example.com/?title=Article-Name will be internal, I won't be able to see ?title=Article-Name on my url bar.

Here is the exception:

If I access m.example.com/Article-Name/ the redirection to m.example.com/?title=Article-Name will be external and now I see m.example.com/?title=Article-Name in my url bar.

So I was expecting the same behavior, if anyone have an idea I will be very thankful.

EDIT:

I have found a solution for the problem but I still interesting about the above problem, about the solution is to use:

RewriteRule ^ ?title=%1 [L]

Please notice: this solution is only needed for m.example.com, I really have no idea how this solution is even working, I have posted this solution because it may help finding the cause for above problem, and how this solution is even working.

EDIT 2(the full .htaccess file):

RewriteEngine On


<If "%{HTTP_HOST} = 'avielfadida.ml'">

# The actual condition is really long one so I replaced it for illustration.
RewriteCond %{HTTP_USER_AGENT} (iPhone|Blackberry|Android) [NC]

RewriteRule ^ http://m.%{HTTP_HOST}%{REQUEST_URI} [R,L]

# I have to duplicate the RewriteCond and RewriteRule both inside the <If> and <Else>
RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]

RewriteRule ^ %{REQUEST_SCHEME}://%{HTTP_HOST}/?title=%1 [L]

# The solution(the solution is not required inside this block):
#RewriteRule ^ /?title=%1 [L]
</If>

<ElseIf "%{HTTP_HOST} = 'm.example.com'">

# I have to duplicate the RewriteCond and RewriteRule both inside the <If> and <Else>
RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%{HTTP_HOST}/?title=%1 [L]

# The solution(the solution is required here):
# RewriteRule ^ /?title=%1 [L]

DirectoryIndex /m/index.htm /m/index.php /m/index.html
</ElseIf>

Important note: there is no relation between the full .htaccess file and the problem, the reason for this update is for the small chance I have made a mistake, anyway I have tested the .htaccess file with only the 3 lines from the question.

HERE IS THE HTTPD.CONF FILE

Last update:

RewriteEngine On    

# The actual condition is really long one so I replaced it for illustration.
RewriteCond %{HTTP_USER_AGENT} (iPhone|Blackberry|Android) [NC]

RewriteCond %{HTTP_HOST} !^m\.example\.com$ [NC]
RewriteRule .* http://m.example.com%{REQUEST_URI} [R,L]

RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]
RewriteRule .* /?title=%1 [L]


<If "%{HTTP_HOST} = 'm.avielfadida.ml'">
    DirectoryIndex /m/index.htm /m/index.php /m/index.html
</If>
