Sorry, I was to fast. Actually situation is like that:

when SERVER_CONNECTED {
    Some test, when failed
    reject

}

Above disables sending 

HTTP::response

When 

TCP::close
is removed then 
HTTP::response
is send.

Why 

TCP::close
executed at serverside disables sending HTTP response on clientside?
