David,
Are you running your applet in the MS JVM? Does the problem appear
when you use Netscape or the Java Plug-In?
There are two features/bugs with Internet Explorer that:
1) limits the number of concurrent HTTP 1.0 connections to four
2) stop object serialization working with HTTP 1.1 connections.
The first problem can cause HTTP requests to block for about
five minutes at a time. There is a registry fix that addresses this.
This problem was breaking an application of mine for a few weeks
and I found scanty documentation on MSDN. The HTTP client
implementation at www.innovation.ch worked around this.

Subject: Applet-servlet doPost using ObjectStreams and MS Personal Webserver
> Folks,
> I'm building an applet-servlet combo for GIS, and I'm using my NT
> workstation for the needed resources (IIS web server and Servlet Exec
2.2).
>
> I'm sending a hashtable containing 5 vectors (very little data, a couple
> dozen bytes) using the example in Hunter's book, and the
> Object(Input)OutputStreams. The servlet takes the object and returns a
> string (dozen bytes). If I buffer the streams at both ends or not, it
makes
> no difference. It takes 5 minutes to complete the transaction! It always
> completes, but it takes way too long.
>
> Is it Personal Web Server, NT workstation, or are there issues with
> ObjectStreams that I need to be aware of? Both hashtables and vectors are
> serializable.
