Double/Multiple execute of bootstrap


  • bootstrap is being executed twice.
  • specified action is being called twice.
  • counter increased twice per hit.


  • Web browser loads a file which is not exist, either through src or href attribute with invalid or empty value (e.g. favicon.ico, global.css, & etc.), web server treats it as “Page not found” error (404).
  • Default configuration for Zend application, the default application (index.php) will handle error 404, an error message “Invalid controller specified” will be displayed, indirectly causing code in bootstrap.php also being executed.


  • Create a favicon.ico in DocumentRoot. and
  • Prevent loading any file which is not exist. or
  • Modify web server configuration (httpd.conf or .htaccess),
    rewrite rule to exclude paths for specified file type.

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} -s [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d [OR]
    RewriteCond %{REQUEST_FILENAME} (.*).(woff|ttf|svg|js|ico|gif|jpg|png|css|htc|xml|txt|swf)$
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^.*$ index.php [NC,L]
