Hmm ... pretty clearly having the client do the transform offloads
work from the server, so what extra resources have you got in mind?
In raw bandwidth terms your claim probably isn't true. And even in
those cases where it _is_ true, it's probably not all that
significant.
Worst case first ...
Server-side transform
n x size of transformed doc
Client-side transform
n x (size of untransformed doc + size of stylesheet)
Now, would you expect the size of the untransformed doc + the size
of the stylesheet to be _vastly_ greater than that of the size the
transformed doc? I wouldn't.
In less worst case circumstances I would hope that the stylesheet
would be cacheable (and cached, either on the client or at an
intervening proxy/surrogate), so we'd have,
Server-side transform
n x size of transformed document
Client-side transform
n x (size of untransformed doc + (size of stylesheet/hit rate))
which makes the client-side transform look a lot more competitive. In
fact, in the not unlikely circumstances that the transform causes
doc size inflation relative to the untransformed doc, the client-side
transform might well have the edge.
So in the absence of solid empirical measurements I'd say this
particular issue was moot.
Cheers,
Miles
