Thanks, Chuck.
We had considered concurrency as an issue. The string in question is entered
into a logging table - every request gets logged, and the log entry includes
a timestamp. So we know there was no other request in process concurrent.
Also, we're not using a Session object to store request-specific data - we
use hidden fields to identify users, and pass the hidden fields form page to
page. (We have our reasons for doing it this way!!)
>From the doPost(...) we simply pass the request object to a method that
does:
Enumeration e = request.getParameterNames();
while(e.hasMoreElements()){
String name = (String)e.nextElement();
strngBldr.append(request.getParameter(name));
}
log(strngBldr); //enters the string into the db along with a timestamp
So we're keeping things as simple as possible.
Also, examining this particular string we find that it contains parameter
name/values from a requqest that was logged hours before this one.
Your thoughts would be deeply appreciated.
Thanks!
Bob

This is pretty much always a problem with incorrect scoping or
synchronization in the webapp. For example, code processing a Request
stores request-specific data into the Session or Servlet object, then
comes back later to find that a different concurrent request has
overwritten it. Or, two request processing threads are accessing a
Session field via some method that isn't synchronized appropriately.
