Getting user's time from web revlet?

Tue Jan 19 09:58:13 EST 2010

Jim,

You've rekindled my interest in using the Revolution engine for cgi on the server. If you keep at it I might even upload a stack or two. 

From your informative post I glommed onto one statement:

"I wonder about the  $_SERVER variables differences."

I have wondered about that also, so I did a little experiment. The summary is that the differences are practically nil.

-----------------
IREV script
goes in public_html folder
-----------------
<HTML>
<?rev

repeat for each key k in $_SERVER
put k & "<br \>" & cr after v
end repeat
sort v
put v

?>
</HTML>

-----------------
Output:

DOCUMENT_ROOT
GATEWAY_INTERFACE
HTTP_ACCEPT
HTTP_ACCEPT_CHARSET
HTTP_ACCEPT_ENCODING
HTTP_ACCEPT_LANGUAGE
HTTP_CACHE_CONTROL  -- only in IREV
HTTP_CONNECTION
HTTP_HOST
HTTP_KEEP_ALIVE
HTTP_USER_AGENT
PATH_INFO          -- called PATH in Rev engine output
PATH_TRANSLATED    -- only in IREV
QUERY_STRING
REMOTE_ADDR
REMOTE_PORT
REQUEST_METHOD
REQUEST_URI
SCRIPT_FILENAME
SCRIPT_NAME
SERVER_ADDR
SERVER_ADMIN
SERVER_NAME
SERVER_PORT
SERVER_PROTOCOL
SERVER_SIGNATURE
SERVER_SOFTWARE

-----------------
REVOLUTION engine
-- script goes in cgi-bin directory
-----------------
#!revolution -ui

on startup

put "Content-Type: text/plain" & cr & cr

put the globals into v
replace comma with return in v
replace "$" with empty in v
sort v
put v

end startup
------------------
OUTPUT:
-- I took off the "$"s 

#                     -- not server variable
0                     -- not server variable

REMOTE_PORT
REQUEST_METHOD
