Does content that has already been written to the out stream affect
forwards? For example the following JSP:
<%@page session="true" language="java" %>
<%!
boolean bSomething = false;
boolean doSomething()
{
return bSomething;
}
%>
<%
if ( doSomething() )
{
%>
<jsp:forward page="./success.html" />
<%
}
else
{
%>
<jsp:forward page="./error.html" />
<%
}
%>
will produce the following code in _jspService when using ServletExec 2.2:
out.print( "\r\n" );
out.print( "\r\n" );
if ( doSomething() )
{
out.print( "\r\n\n\n" );
if ( true )
{
pageContext.forward( "./success.html" );
return;
}
out.print( "\r\n" );
}
else
{
out.print( "\r\n\n\n" );
if ( true )
{
pageContext.forward( "./error.html" );
return;
}
out.print( "\r\n" );
}
out.print( "\r\n\r\n\r\n" );
Ignoring the inefficiency of this, I just want to make sure that the
extraneous out.print() calls are not going to mess up the data stream that
finally needs to get to the client.

Ghosh,
The forward tag is invisible to the browser. As far as the browser is
concerned, it requested a specific resource form
the server (identified by the address in the browser). That resource was
returned - the actual contents of that resource
(in this case, obtained on the server side by forwarding to page 2) don't
matter. If you want to see the address of page
two in the browser, you must use a sendRedirect to make the browser request
resource page 2.
