Answer 2

<Directory /var/www/bitrix-test.klondike-server.ru/web/upload>
    AllowOverride none

<IfModule mod_mime.c>
     <Files ~ \.(php|php3|php4|php5|php6|phtml|pl|asp|aspx|cgi|dll|exe|shtm|shtml|fcg|fcgi|fpl|asmx|pht|py|psp|rb|var)>
          SetHandler text/plain
          ForceType text/plain
