Htaccess Query String Conflicts

I would lile to rewrite urls by passing domain, sub-domain and request uri to a php file by a query string with the following .htaccess

# Apache configuration

    Options -Indexes
    Options -Multiviews
    Options +FollowSymLinks


# Rewrite engine configuration

    RewriteEngine on
    RewriteBase /


# Sub domain redirection (301 redirect)

    RewriteCond %{HTTP_HOST} ^([^\.]+\.[^\.0-9]+)$
    RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]


# Request redirection

    RewriteCond %{HTTP_HOST} ^([^\.]+)\.([^\.]+)\.[^\.0-9]+$
    RewriteRule ^(.*)$ index.php?app=%2&sub=%1&req=$1 [QSA,END]

Here are some working examples :

http://dev.testdomain.tld/hello/world

=> /index.php?app=testdomain&sub=dev&req=/hello/world

And

http://www.example.tld/?var=test

=> /index.php?app=example&sub=www&req=/&var=test

But if i have something like this :

http://dev.testdomain.tld/hello/world?app=FAIL&sub=FAIL&req=FAIL

=> /index.php?app=testdomain&sub=dev&req=/hello/world&app=FAIL&sub=FAIL&req=FAIL

The query string will replace domain, sub-domain and request uri variables with FAIL (or everything else from url query string). I could desactivate [QSA] flag, but i would like to keep the original query string, and prevent app, sub, req variables rewriting.

You could remove the app, sub and req parameters from your query string and use the PHP $_SERVER var. This PHP superglobal contains some interesting values to solve your problem:

http://dev.testdomain.tld/hello/world?app=FAIL&sub=FAIL&req=FAIL

var_dump($_SERVER);

Will lead to the following output:

array(...) {
  ["HTTP_HOST"]=>
  string(13) "test.test.tld"
  ["QUERY_STRING"]=>
  string(9) "hahah=w12"
  ["REQUEST_URI"]=>
  string(28) "/~stejanse/tst.php?hahah=w12"
}

You could use these variables to retrieve your information instead of using mod_rewrite.
