The problem is that Tomcat is compliant with the Servlet specification, 
and as Mark pointed out in the original ticket #47410 that is part of 
the spec.

This is not a Tomcat-specific solution.  I use it with Jetty as well.  
It does use a library from Apache for processing FileUpload, and if you 
are running Tomcat you already have it in your classpath, but if you are 
not, you need to add that jar.

I've never had an issue with that, and am not sure what you are worried 
about?  network traffic?  memory? (the FileUpload library writes the 
contents to disk after a certain threshold), but if you're concerned 
with that then you can write your own filter and model it after mine if 
you want to hit the ground running.  Then you can break the read 
whenever you want, though I really think that you're over-optimizing here.

TBH I did not read your original emails with Chris in full, so I'm not 
sure what your requirements are.
