RequestDispatcher and sendfile()/java.nio

[Ronald Klop <ro...@base.nl>]

Hi,

Does Tomcat 5.5 or maybe 6.0 use java.nio/sendfile() to send static content?
So is it more prefered to use RequestDispatcher.forward(myfile) than copy a FileInputStream to ServletOutputStream by hand?
I already have the copying part, but would like to know if it is worth the trouble to rewrite it to the dispatcher. I would have to shuffle quite some files, so the rewrite isn't like a couple of minutes work. ;-)

Ronald.

6.0 uses sendfile, you can manually trigger send file too by just 
setting attributes

check out DefaultServlet.java
search for sendfile and setAttribute on the same line
