# Download Managers
# These handle downloads of files to be filtered and scanned.

# Normally the browser can just wait, but with content scanning,
# for example to AV, the browser may timeout or the user may get
# confused so the download manager has to do some sort of
# 'keep alive'.
#
# There are various methods possible but not all are included.
# The author does not have the time to write them all so I have
# included a plugin systam. Also, not all methods work with all
# browsers and clients. Specifically some fancy methods don't
# work with software that downloads updates. To solve this,
# each plugin can support a regular expression for matching
# the client's user-agent string, and lists of the mime types
# and extensions it should manage.
#
# Note that these are the matching methods provided by the base plugin
# code, and individual plugins may override or add to them.
# See the individual plugin conf files for supported options.
#
# The plugins are matched in the order you specify and the last
# one is forced to match as the default, regardless of user agent

# Multiple plugins can be specified, and will be queried in order until one
# of them either finds a username or throws an error. For example, if Squid
# is configured with both NTLM and Basic auth enabled, and both the 'proxy-basic'
