[racket] web server: CRUD put/delete?

Hi all,

I'm using 6.0.1 trying to implement a CRUD interface, but  the 
dispatch-rules doesn't seem to recognize PUT or DELETE as valid methods 
- they both are interpreted as GET.

Is dispatch-rules limited to HTML 1.0 (i.e. only GET, POST and HEAD)?

Has this been updated since 6.0.1?  The current 6.1 docs for 
dispatch-rules appear to be the same.

Thanks,
George
