Re: I'm trying to use wml in a cgi...

Sorry this is so long in coming...
I unset the content length (yes, it was a post) and that solved _a_
problem. It just let m find the next one. e-Perl woulc complain about not
wanting to work over a file in /tmp with the wrong extension.
On a hunch, I nuked all the CGI related environment before invoking wml,
and that solved that. Sorry, I haven't done an exhaustive investigation, I
just know one or more of those vars was the culprit, since it works now.
[L]inux has an installed base conservatively estimated at around 3 million
users.... [V]endors say that most of the top companies in the US have bought
the OS - but that few will readily admit to running their multimillion-dollar
corporations on code put together by a band of software idealists. -- _Wired_
