This is a reply to the group rather than just you, but when shopping for
virtual web space, be sure your provider runs a wrapper program like
suEXEC or cgi-wrap or something. Actully, the only wrapper I reccommend
is suEXEC. What this does is change the permissions a script runs as to
the permissions of the script's owner. That way, you can leave your cgi
programs 700 and the text files (and directories) you write to 600. This
secures your data very tightly.
Run this program through a web browser:
#!/usr/bin/perl -w
use strict;
use CGI qw/:standard/;
print header();
print start_html();
print div('Apache user:');
print div('I am:', `id -un`);
print end_html();
And if it says the program runs as anyone other than you, tell your host
that you want suEXEC. If that dosent work, find another host.
