( #3333=superdoc: print w/replies, xml ) Need Help??

This isn't possible with CGI. The CGI RFC doesn't define any mechanism for determining the order of the headers. Additionally, environment variables in general don't have a defined order, and Perl's %ENV hash is randomized. The only way to do this would be to have a different mechanism of communicating with the server software such as ig's mod_perl example.

It wouldn't be possible to do this in PHP for scripts run as CGI either. Assuming you meant PHP's getallheaders function, it is even documented as only working when running as an Apache module.

    [stevieb]: I find the M::S makefiles it generates are quite straight forward, and I usually have to add a few things (github info etc). They're about 15 lines or so give or take.
    [Corion]: I don't think the EUMM-generated Makefile is that complicated ;)
    [stevieb]: Corion++
    [jedikaiti]: RonW++ #I have so much accumulated in my memory that finding the right item at a given moment often fails
    [LanX]: corion only > 800 lines
    [stevieb]: ahhh you're talking about the actual Makefile, not the PP Makefile.PL
    [Corion]: LanX: But most of that is just setup of variables to be used later, like CC , LIB etc.
    [LanX]: yes and some builders try to avoid it
