Just stop using CGI.pm to produce HTML. Use templates instead. Sorry, I
know that sounds like harsh advice, but you won't regret it in the long
run.

We had the same problem with -oldstyle_urls.

Below is what I did because I didn't know better. Enlightenment welcome.


from startup.pl (you would use $XHTML):

use CGI qw(-compile -oldstyle_urls :all);
#
# override CGI::initialize_globals to avoid the default for 
# $CGI::USE_PARAM_SEMICOLONS (we always use -oldstyle_urls)
#
# Caution:
# This works as long as NO script explicitly uses -newstyle_urls. 
#
# Background:
# CGI.pm registers an Apache cleanup handler to call reset_globals,
# which in turn uses initialize_globals. Since _setup_symbols
# (which handles the -oldstyle_urls option) runs only once
# for every httpd-instance under mod_perl this option works  
# only for the first ~MaxServers invocations of the script.
#
my $real_initialize_globals = \&CGI::initialize_globals;
undef *CGI::initialize_globals;
*CGI::initialize_globals = sub {
&$real_initialize_globals();
$CGI::USE_PARAM_SEMICOLONS = 0;
};

really odd XML + CGI.pm + mod_perl + Macintosh + IE 4.5 problem

[Jason Terry]

OK I have ben RTFMing for about 5 hours now and I did find a fix for part of my 
problem

It seems that Mac browsers (IE 4.5 and an old AOL that I know of) are having trouble 
viewing our HTML producing CGI scripts that use
a function called &CGI::start_html()

Apparently (recently in CGI.pm) there has been a change where the CGI::start_html 
includes the following


This tag is reaking havoc on some browsers on Mac and possibly others.

Well after pouring through the "perldoc CGI" I found that if you
use CGI(:all -no_xhtml);

then you will not get the compile(qw(:all -no_xhtml));#used to optimize CGI.pm memory consumption for 
forked processes

and I have this in the 2 scripts that I actually use in mod_perl
use CGI qw(:all -no_xhtml);

my problem is that in mod_perl... it still occasionally prints the
