Subject Re: Urgent: how to detect client has closed connection
Date Thu, 02 Jun 2005 20:25:12 GMT
Hey Ronald,

Thanks for your help. I checked the code. I use default out.. and it indeed 
was using javax.servlet.jsp.JspWriter, but it does not throw an IOException. 
Do you know why?

Thanks in advance...
