Chris,
That makes more sense.
So MapBuilder is magically noticing the WMS-C in your URL and
converting its requests to a tiled mode. Unfortunately, Mapserver does
not understand the WMS-C keyword and is croaking, even though there is
no functional difference (from a WMS PoV) to serving a WMS-C request
and a WMS request.
A quick and dirty fix would be to write a small PHP script to sit in
front of mapserver, convert the WMS-C to a WMS and then pass the
request onwards.
Alternately (and more elegantly), perhaps there is some way to trick
mapbuilder into the tiled mode without the WMS-C keyword in the URL?
Check your Mapbuilder docs.

Hi Paul,
I am using MapBuilder's latest instance, which renders with Open
Layers, and is capable of tiling. I load an initial map, querying a
local http server and designating the WMS service type as WMS-C,
and, voila, rendering of tiles where previously (service type plain
WMS) the entire viewport is rendered as one. When I attempt a
similar request of my MapServer instance, which handles all of my
hosted raster imagery, I get the error:
mapserv(): Web application error. Traditional BROWSE mode requires a
TEMPLATE in the WEB section, but none was provided.
Which I meant to include in my first post, sorry. Any guidance?
Thanks,
Chris

Chris,
Tiling is a property of the client, not the server... the client
breaks the problem of filling the viewport up into files and sends
the
tile requests, usually in parallel, to the server. What user
interface are you building with?

Hello,
I would like to take advantage of the expediency of visual
feedback afforded
by presenting my raster image as a mosaic of tiles, rather than
the user
waiting for, for example, a single .png in my viewport- typical,
now-ubiquitous tiling behavior.
I am able to initiate a WMS query with service type WMS-C (i.e.
SERVICE=WMS_C) successfully to another service, but am
unsuccessful when
querying through my MapServer instance. Is it possible that
MapServer
doesn't support WMS-C? Hopefully, it is just my ignorance. I
confess that
I merely changed my existing URL-encoded string, replacing WMS
with WMS-C
(pretty optimistic, huh!). I believe my shapefile refererenced by
the
mapfile is properly comprised of appropriate tile images. Can you
straighten me out, please?
Thanks,
Chris
