You can reference indirect styles using SLD=<http url>.
NOTE: THESE HAVE TO BE <NamedLayer> or <UserLayer> elements in the SLD -
and it has to completely define the request. Please read the SLD spec
before you try this as you'll almost certainly get it wrong!! I'm
going to be fully documenting this starting sometime next week.
There are 4 ways to send SLD to Geoserver:
a) (http get) SLD=(URL) geoserver makes an http location to the SLD and
loads it
b) (http get) SLD_BODY=... send an SLD file to geoserver using GET
c) (http post) WMS GetMap 1.2 request Send the SLD (and other request
parameters) in a POST XML document. This is how the SLD spec says you
should do it.
d) (http post) GET Parameters, SLD in the Post Use http GET for the
parameters (ie. location and image size) and use POST for the SLD

ps. wait for beta4 to come out (friday hopefully) - it has much better
SLD support.
