# Generate a list of unique URLs, each of which resolving to the same trival
# HTML file.  I don't see an easy way of specifying zero rewriters (default is
# CoreFilters) but by specifying a single rewriter "rewrite_domains" as a
# query-param, we can emulate that.  Note that "rewrite_domains" doesn't do
# anything if there are no domain-mappings set up.
#
# TODO(jmarantz): There appears to be no better way to turn all
# filters off via query-param.  Though you might think that
# PageSpeedRewriteLevel=PassThrough should work, it does not.  There
# is special handling for PageSpeedFilters=core but not for
# PassThrough.
