Q: request replication

[Michael Wentzel <Mi...@aswethink.com>]

I am having a unique situation pop up.  It's some
kind of concurrency issue but I can't figure out
what's causing it.  I am generating PDFs in a servlet
and a single request to the servlet works fine but
if two users request a PDF at "roughly" the same time
then the adobe plugin appears to get confused and
doesn't display the generated file.  Each users request
is actually getting made 3 times(using the same request
object) to generate 3 unique files(servlet generates
unique file ids).  I have removed AutoSetup ContextInterceptor so there is
only one instance of the servlet and the jsp calling the servlet is only
making a single request.  The first request for each PDF has a Referer and a
request.getRequestURI() each subsequent(duplicate) request does not have a
Referer.  Any suggestions would be appreciated.

I'm seeing some messages regarding multiple request from internet exploder.
Do you have the same problem with nutscrape? A couple of messages back I
also read that all messages regarding multiple request from exploder are
closed, because it wasn't reproducable. Maby you can give this a go on
nutscrape and tomcat 33 to see if the problem is reproducable there..

Mvgr,
Martin
