Yea,
I guess the syntax could be key, although I would think the logic of the one
I referenced would have worked as well, but it did not. The pipes are
already doing an OR without the parenthesis. I would not leave it to chance,
and lab it up. I know it will work correctly as long as you select only one
picture type. So if I download a .gif, the policy matches, but then if I
download a jpg, it does not match. I tried this with all sort of different
combos, same effect each time. Maybe the parenthesis will fix it.
match-any works, nested under a match-all, which is essentially the same
logic as
match protocol http url "*.jpg|*.gif|*.jpeg" Or you can create a separte
class-map for each image type, and force the policy on each type. I dunno. I
am still curious.
