no Sean. You are likely confusing QUERY_STRING with PATH_INFO (these
are the cgi environment variables that populate the ENV hash).

PATH_INFO refers to the portion _after_ the immutable part of the URI.

so, the non-changing part of my URI is ../index.cgi and everything
after that becomes PATH_INFO.

C-A 3.31 provides a shortcut to grab PATH_INFO by setting
mode_param(path_info => 1)

yes, but you can also provide runmodes as an anon array as long as the
runmodes themselves are named exactly as the calls they are gonna
make.

so the above can be shortened to run_modes([qw/welcome login/])

Thanks anyway.
