Sorry, I'm not following your comment. I've suggested to test with mod_cgi (under Apache2), since mod_perl mimics mod_cgi's behavior here.
I changed the handler in httpd.conf from perl-script to cgi-script and the problem went away.
Should POST-redirect return 307? http://ppewww.ph.gla.ac.uk/~flavell/www/post-redirect.html http://rfc.net/rfc2616.html#s10.3.8
"303 See Other" is the correct post-POST redirect response: http://rfc.net/rfc2616.html#s10.3.4 which your first link suggests works in all browsers.
CGI.pm always returns a 302, though, if necessary, I can edit its reply in my script before printing it. I'll give this a go.
Thanks -- Mark
