Folks,
Going to try this again since I got no reply to my first inquiry. I'd
like to log a bug report along the lines of "request getAttributeNames
method does not return all request attributes (e.g.,
org.apache.tomcat.sendfile.support)". Either that or this is a doc
issues somewhere. I know in the scheme of things this is not an
earth-shattering issue / bug, still it's apparently not working
correctly.
I would put this one of two ways, either:
1. The Tomcat HttpRequest getAttributeNames method has a bug and
doesn't return the attribute like org.apache.tomcat.sendfile.support
(even though I can access that attribute via the getAttribute method);
or
2. There's a doc error in the getAttributeNames doc where the cases
where it doesn't show all attribute names needs to be explained.
My original message on the topic is below.
Thanks!
Chris
