Yes and no. It has the same responsibility in the "Seaside stack" but
is "object oriented" and not "string/byte array oriented" and more
high level.

Well the "problem" is that "traditional" servers (Comanche, Swazoo,
OpenTalk) used to "object oriented" and fully featured web servers.
Since building something like that takes a lot of work more recent
servers (FastCGI, SCGI, AJP) are "string/byte array oriented". The
later ones are obviously easier to adapt to a ring/rack/wsgi style
