Yes. You can have both an mc-based browser or html forms speaking to the server.
But the first way will only run fine if the mc-based browser speak directly to
an mc vpn deamon, not to a standard httpd (i.e.: Apache, WebStar, IIS...).

It's a way to have mc running as a web application server (WAS, i.e.: Zope or
ColdFusion) instead of just a cgi interpreter. If you use this way, you will be
able to run your MC-based WAS in both root-console mode (on a "<= 1024 socket
port") and standard user-x-windows mode (on a "> 1024 socket port"). If the
first mode is prefered as the "production" mode, the second mode is usefull as
the "programming & debugging" mode (you can use the "put" and "answer" commands
to parse the code to debug).
Be just carefull not to use "on idle" handlers in your WAS as far this is only
working in graphical mode, not in the console mode.

The same as above ;-)

I never found the way, for yet, to have the MC-based WAS linked to Apache trough
an ".mc/.mt" cgi based script. I use an ".php" based script, renamed as ".xml",
instead and it works fine :
<?
if ($REQUEST_METHOD == POST) {
$headers = $HTTP_POST_VARS;
while (list($header, $value) = each($headers)) $exAE .= "$header=$value&";
$exAE = urlencode($exAE);
$connection = fsockopen("localhost", "567", &$error_number,
&$error_description, "30");
if ($connection) {
set_socket_blocking($connection, true);
fputs($connection,"");
fputs($connection,"$exAE"."\r\n");
fpassthru($connection);
}
else {
$connection = fsockopen("localhost", "4567", &$error_number,
&$error_description, "30");
if ($connection) {
set_socket_blocking($connection, true);
fputs($connection,"");
fputs($connection,"$exAE"."\r\n");
fpassthru($connection);
}
else print("erreur num�ro $error_number ($error_description)<BR>\n");
}
}
else print("<HTML><HEAD><TITLE>ERROR: File Not Found</TITLE></HEAD>".
"<BODY background='/gif/fond-maison.gif'><H1>File Not Found</H1><P>".
"<H3>The file you have requested does not exist on this
server.</H3></BODY></HTML><BR>\n");
?>
If you want to use this MC-based WAS way, just create a new stack and put this
in the stack script :
on newconnect s
read from socket s for 1 line with message "serverread"
end newconnect
on serverread x,y
global PostIn,Retour,Lepath
put urldecode(y) into PostIn
put cr into char (length(PostIn))-1 to (length(PostIn)) of PostIn
put empty into Retour
set itemdelimiter to "&"
doswitcher
write Retour to socket x
close socket x
end serverread
on socketTimout
end socketTimout
on doswitcher
global PostIn,Retour
set itemDelimiter to "&"
if char 1 to 6 of item 1 of PostIn is "hello="
then hellotest
end doswitcher
on PreOpenStack
global Masq,AccPpx,Lepath
put " Please, wait. WMC server loading..."
set twelveHourTime to false
put "WMC TCP/IP SEARCH/DB/APP'S server up since" && the short date & "," &&
the short time into binfo
# put "/usr/local/httpd/w-max/iassd/" into Lepath
# put url (Lepath & "ia9312.html") into Masq # store your html headers/footers
there
# open file Lepath & "COLia931.txt" for read # load the needed data as global
vars
# read from file Lepath & "COLia931.txt" until eof
# put it into AccPpx
# put " " & the result after pboot # test the path
# close file Lepath & "COLia931.txt"
put " eof" into pboot # to comment if you need to uncomment the above lines
set the socketTimeoutInterval to "10" # don't forget !
if the windows is "wasstack" # the default name of your was main stack
then accept connections on port "567" with message "newconnect" # console mode
else accept connections on port "4567" with message "newconnect" # x-windows
mode
replace " eof" with "" in pboot
if the num of words in pboot > 0
then put "WMC not up :" & pboot
else put binfo
end PreOpenStack
on HelloTest
global Retour
put "<HTML><BODY><FORM> into Retour
put "<table border='0' cellpadding='0' cellspacing='5' width='100%'
bgcolor='#EEE8AA'><tr>" & \
"<td align='center'><font size='2'><B>Hello world
!</B></font></td></tr></table>" after Retour
put "</FORM></BODY></HTML>" after Retour
end HelloTest
3.- ... and don't forget to add :
<FORM ACTION="wmc.xml" METHOD="POST">
<INPUT TYPE=HIDDEN NAME="hello" VALUE="1">
to your HTML WAS querying form.

If there is others usables ways to get fine Web Apps running, i prefer, for
myself, the MC way because MC is able to serve VPN apps too, because MC is lots
more powerfull than Java, Python, Perl, etc...

Please !?? Do never talk to a distant server in using the unsecure Telnet
protocol. Install and use an SSH deamon instead to stop, start or reboot your mc
app...

To play this way, just remember that "...the first way will only run fine if the
mc-based browser speak directly to an mc vpn deamon".
