Method Detail

doFilter

public void doFilter(HttpExchange exchange)

calls the next filter in the chain, or else the users exchange handler, if this is the final filter in the chain. The Filter may decide to terminate the chain, by not calling this method. In this case, the filter must send the response to the request, because the application's exchange handler will not be invoked.

IOException - let exceptions pass up the stack

NullPointerException - if exchange is null
