Cara konversi mod rewrite ini gimana ya?

RewriteEngine On
RewriteCond %{REQUEST_URI} ^(.+)\~s$
RewriteRule ^(.*) stats.php?u=$1 [L]
RewriteCond %{REQUEST_URI} ^(.+)\~d$
RewriteRule ^(.*) delete_file.php?u=$1 [QSA,L]
RewriteCond %{REQUEST_URI} ^(.+)\~i$
RewriteRule ^(.*) share_file.php?u=$1 [QSA,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !\.html$
RewriteRule ^(.*) file_download.php?u=$1 [QSA,L]

RewriteRule ^(.*).html$ $1.php [L]

coba ini:

location / {
if ($request_uri ~ "^(.+)\~s$"){
rewrite ^/(.*) /stats.php?u=$1 break;
}
if ($request_uri ~ "^(.+)\~d$"){
rewrite ^/(.*) /delete_file.php?u=$1 break;
}
if ($request_uri ~ "^(.+)\~i$"){
rewrite ^/(.*) /share_file.php?u=$1 break;
}
if (!-e $request_filename){
rewrite ^/(.*) /file_download.php?u=$1 break;
}
rewrite ^/(.*).html$ /$1.php break;
}
