Thanks for the suggestion. It does not seem to help, though. I think the
issue has less to do with form content going from the browser to the server
than it does with large hunks of pdf content going from the server to the
browser.

Try the following it helped us:
-Dorg.mortbay.http.HttpRequest.maxFormContentSize=${MAXFORMCONTENTSIZE}

I'm having a problem getting a Jetty server to serve up a large (1 mb) pdf
file. When I click on a link that points to the pdf, IE downloads about half
of it (according to the kb count in the status bar) and then freezes. If you
try it a couple more times then sometimes IE will display it. Firefox
immediately says "stopped" in the toolbar and displays nothing.
The server is running locally, so this is not a problem getting the file
across a bad connection.
I can open the pdf fine in Acrobat directly. I can also serve it up fine
under Resin -- both IE and Firefox can connect to a Resin server and display
the file without a problem.
I see the problem with both Jetty 5.1.1 and Jetty 5.1.4.
Now here's the really tricky part: I'm running Jetty in my app as an
embedded server. If instead I run it from a default Jetty installation,
using start.jar, then there is no problem. The pdf displays fine. So my
guess is that this is configuration issue. I'm having the server load
webdefaults.xml, so that configuration should be correct.
Where else should I be looking for this problem?
Here's the code I use to run the server in the app (slightly edited). I can
make the pdf available, if necessary.
