+Remapping
+---------

+One of the biggest changes in ATS v9.0.0 is that URL rewrites, as specified in
a :file:`remap.config`
+rule, now always happens **before** all plugins are executed. This can have
significant impact on
+behavior, since plugins might now see a different URL than they did in prior
versions. In particular,
+plugins modifying the cache key could have serious problems (see the section
below for details).

Platform specific

Solaris is no longer a supported platform, but the code is still there.
However, it's unlikely to work,
and unless someone takes on ownership of this Platform, it will be removed
from the source in ATS v10.0.0.
