eris implements el-cheapo HTTP ranges (only byte ranges and only of the
form x-y, not multiple ranges).
eris implements content type matching and Accepts: parsing, but the
content type table is compiled in, i.e. to change it, you have to change

in the query before trying to answer them.

If eris is given the -c option, it will regard files
whose names end with ".cgi" as CGI programs and try to execute them.

CGIs.
Please see <http://hoohoo.ncsa.uiuc.edu/cgi/interface.html> for the CGI specification.
