hi,
thanks for the reply - you confirmed what i suspcted (that this isn't
common).
just fyi, looking at the global grid forum's software (ggf being the
academic grid people, as far as i can see) they seem to be using a java
package called puretls, which might do this. so i'm going to have a look
at it today.
to be honest, i doubt that we could commit to using anything that doesn't
already exist (i'm supposed to have something ready for demonstration in
january and we're still designing the security), but i guess it would be
useful to keep it in mind as a possible future extension (if i understand
correctly it's an obscure but very useful little trick for distributed
security - lets the code on the server use transport layer security in the
name of the client - but it's quite possible that the future is message
layer security for this kind of thing). the pluggable handler idea sounds
like a decent solution (although i don't know much about all this).
cheers + thanks again for the reply,
andrew
