I had a similar problem when using response.sendRedirect(). I don't know
whether the same applies to you, but in our our code we had a section like:
<% if( some_condition )
response.sendRedirect(another_url);
%>
<html stuff>
The problem is that response.sendRedirect() sends off the forward request to
the browser and continues to output the html because there is no return or
else statement blocking it ( programming oversight:-( ). In combination
with http keep-alives, this means that sometimes the rest of the jsp file is
outputted simultaneously down the same socket connection as the newly
requested file from the sendRedirect(). This exceeds the content-length that
has been calculated for just one file and causes the error.
I don't know whether this can be classed as an Orion bug ( not synchronizing
access to sockets ) or a programming error ( not returning or elsing the
sendRedirect() ).
If the above example is changed to
<% if( some_condition )
{
response.sendRedirect(another_url);
return;
}
%>
<html stuff>
then everything works fine.
