php - Cannot access subpage url of subdomain -

i did rewrite rule wildcard subdomain access allow me access countries of list page follows:

    rewritecond %{http_host}    ^(.+)\.mydomain\.net$     rewritecond %{http_host}    !^www\.mydomain\.net$     rewritecond %{request_uri}  !^.*\.(jpe?g|png|gif|bmp)$ [nc]     rewriterule (.*)            pages/list.php?country=%1 [l] 

this working fine.

now. rewrite rule access page on domain keep getting referred list page.

    rewriterule    ^ad/([a-za-z0-9-]+)?$        pages/details.php?alias=$1                                          [nc,l] 

my end result access eg: http://us.mydomain.net/ad/alias keeps referring me list page.

updated rewrite rules(as of 14 may)

        rewriteengine on          <ifmodule mod_headers.c>            header set access-control-allow-origin "*"         </ifmodule>          rewriterule ^cat/([a-za-z0-9-]+)/?$ ?category=$1 [l,qsa,nc]          rewritecond %{request_filename} !-f         rewritecond %{http_host}    ^(.+)\.ibizportal\.net$         rewritecond %{http_host}    !^www\.ibizportal\.net$         rewritecond %{request_uri}  !^.*\.(jpe?g|png|gif|bmp)$ [nc]         rewriterule (.*)            pages/list.php?country=%1 [l] 

change first rule to:

rewritecond %{request_filename} -f [or] rewritecond %{request_filename} -d rewriterule ^ - [l]  rewriterule ^cat/([a-za-z0-9-]+)/?$ ?category=$1 [l,qsa,nc]  rewritecond %{http_host} ^((?!www).+)\.mydomain\.net$ [nc] rewritecond %{request_uri} !\.(?:jpe?g|png|gif|bmp|php)$ [nc] rewriterule (.+) pages/list.php?country=%1 [l,qsa]
