demo.mapserver.org is not FastCGI (hence why it is so reliable ;)

I keep an updated build note at bottom of demo.mapserver.org homepage, let me know if other details are needed.

So for sure https://demo.mapserver.org/cgi-bin/wms <https://demo.mapserver.org/cgi-bin/wms> is FastCGI? This seems like it might be kinda hard to debug.

    Hi,____

    I have seen those http 500 errors but I do not remember in what
    circumstances. What I do remember is that I was awaiting for some
    other message that I was used to see and getting past the 500 error
    required prior knowledge about what might be wrong. Not very useful
    but at least you know that you are not totally alone. Issue does not
    happen on our demo server https://demo.mapserver.org/cgi-bin/wms
    <https://demo.mapserver.org/cgi-bin/wms>.____

    By the first message you got it seems that your initial bare request
    is effectively not the most initial but the default mapfile is added
    to the query. Otherwise the message would be shorter “No query
    information to decode. QUERY_STRING is set, but empty.” Probably
    that does not matter but maybe there is something to test about
    SetEnv or SetEnvIf or whatever you have used in the Apache
    configuration.____

    Hi all: It might be surprising but I've not used FastCGI much
    over the years and am diving in w/8.0. I'm using SuSE Linux and
    running into an issue with error messages. For example an initial
    bare request (e.g. https://myhost.com/cgi-bin/mapserv.fcgi
    <https://myhost.com/cgi-bin/mapserv.fcgi>) generates the expected
    message " loadParams(): Web application error. No query information
    to decode. QUERY_STRING is set, but empty.". However, a second
    request (and any subsequent requests) generates a 500 error. Any
    requests that would normally create a map, query, etc... resolve
    normally so it seems to be limited to typical CGI error messages.
    Has anyone run into this issue?____
