My problem is similar but different. First, the client/user is not disconnecting - knowingly anyway. (Unless the browser is disconnecting on it's own for some reason.) When I am able to reproduce this, the browser gets back some of the output, but not all . I am not manually disconnecting - once again it would be the browser.
Second, I have been able to reproduce this using Netscape 7.0 as the client. Therefore, it is not isolated to IE. Maybe the problem is the same, but is not restricted to just IE? -----Original Message----- From: John Trollinger [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 12, 2002 9:52 AM To: 'Tomcat Developers List' Subject: RE: Problem with Socket closing See bug 12810 > -----Original Message----- > From: Greg Strobl [mailto:[EMAIL PROTECTED]] > Sent: Thursday, December 12, 2002 9:38 AM > To: '[EMAIL PROTECTED]' > Subject: Problem with Socket closing > > > Hi, > > Tomcat 4.1.12 > OS: W2K > JRE: Sun 1.4.1_01 (Originally found using 1.4.0) > > I am seeing a problem with Tomcat closing a socket connection > and having a write error.
