Sorry for the late reply.

I was going to write that IIS sends a wrong header according to the
RFCs, but after re-reading them I now think that one might interpret
them in a different way and that Drakma's general handling of commas
has to be reworked to accommodate this interpretation.

Stay tuned, I'll think about how this can best be achieved.

Edi.
