It's a dynamic redirect. <http://imgs.xkcd.com/comics/now.png> redirects
to <http://c.xkcd.com/redirect/comic/now>, which redirects to a URL of the
form "http://imgs.xkcd.com/comics/now/HHhMMm.png", where "HH" and "MM"
are digits specifying a time of day, in UT+12h, rounded to a multiple
of 15 min. The second redirect has HTTP headers to disable caching.
