I seem to recall reading in the haproxy manual that regex matches are
generally a lot slower than other kinds of matches. So, if you can do a
'path_beg' match, for example, that's a better performing choice over a
'path_reg' match which would accomplish the same thing. Given you have
mentioned that 'STARTS_WITH' and 'ENDS_WITH' are listed as compare_types
we're enumerating, I guess this has already been taken into account?
