Page 293 , the author gives an example of nestling rewrite maps 1)RewriteMap giftojpg txt:/usr/local/apache/rewritemaps/gif_to_jpg.map
2)RewriteMap jpgtopng txt:/usr/local/apache/rewritemaps/jpg_to_png.map
3)RewriteRule ^(.*)/([^/]+)\.gif $1/${jpgtopng:${giftojpg:$2|$2}|$2}.jpg
Should the line 3 not be like this:
RewriteRule ^(.*)/([^/]+)\.gif $1/${jpgtopng:${giftojpg:$2|$2}.jpg|$2}.png
