I'm trying to convert a small tool to use PerlEx (on IIS) for performance however it seems like there is no way to access the HTTP headers from the client request in this mode. When using the CGI mode in IIS with perl.exe I see them fine, but they vanish when using PerlEx30.dll. I'm testing using curl to send a custom header that I want to grab on the server side. Here is the output from a test script against both server side methods. 
D:\>curl https://localhost/debug.pl -H "Token: 3cc8bbeb" -X POST -F Te
+st=Test
$VAR1 = 'HTTP_ACCEPT';
$VAR2 = 'HTTP_USER_AGENT';
$VAR3 = 'HTTP_HOST';
$VAR4 = 'HTTP_CONTENT_TYPE';
$VAR5 = 'HTTP_TOKEN';
$VAR6 = 'HTTP_CONTENT_LENGTH';
$VAR7 = 'HTTP_EXPECT';

D:\>curl https://localhost/debug.plex -H "Token: 3cc8bbeb" -X POST -F 
+Test=Test
$VAR1 = 'HTTP_USER_AGENT';

The simple script on the server side is the same in both files: 
use CGI qw(:standard);
use Data::Dumper;
my $session = CGI->new();
print "HTTP/1.1 200 OK\n\n";
print Dumper($session->http());
