# Comment:
# the CGI::Upload call under -w causes a warning in the CGI module that is reported as one of these:
# Use of uninitialized value in pattern match (m//) at (eval 8) line 4
# this hapens if the HTTP_USER_AGENT is not defined

# On the other hand HTTP::BrowserDetect complains heavily if the HTTP_USER_AGENT is not something
# it expects. e.g. this one:    $ENV{HTTP_USER_AGENT} = "Linux";
# This is not very related to CGI::Upload but well.


# If I copy-paste the whole section of the upload, the second section does not
# work correctly. Is this a bug or a user error ?
