Subject Connection draining when upload to large
Date Thu, 10 Feb 2011 13:04:31 GMT
Servlet 3 standardizes file uploads. It contains the ability to limit on 
request size, pretty much the same as commons fileupload supported for 
many years.

It seems when this conditions triggers the rest of the request inout 
stream is still drained at the end of the request. swallowInput is not 
being set to false.

It seems there's still no server-side prevention against huge uploads 
possible. The upload is not put into memory, but the thread is only 
freed once the whole request body is read. Shouldn't Tomcat ignore the 
rest of data and close the connection in this case?

Regards,

Rainer
