Printing environment variables:

Let's print out <i>all</i> the environment vars we get from the HTTP request:<br/>
<?
local env = getEnv();
for key,value in pairs(env) do
    ?>
        <b><?=key?>:</b> <?=value?><br />
    <?
end
?>

Reading form data:

<form method="post">
<input type="text" name="name"/>
<input type="hidden" name="action" value="post stuff">
<input type="submit" value="Submit"/>
</form>
<?
local params = parsePost();
if (params and params["name"]) then
    echo("Hello, ", params["name"], "!");
end
?>

Printing a text-only page

<?
setContentType("text/plain");
?>
Plain text goes here, and any <html> tags should not be parsed.

Sending a file directly to the browser

local filename = "abcdefg.txt";
setContentType("text/plain");
file.send(filename); --# Use sendfile to maximize performance

Including scripts and files

<?
include("myheader.plua");
echo("Contents goes here");
include("footer.html"); --# You can include HTML files as well
?>

Redirecting to another URL

<?
header("Location", "/gone");
setReturnCode(302); --#Set httpd to return 302 Moved
print("We have moved!");
?>

Basic WWW-authorization

~~~~~~
<?
header("WWW-Authenticate", 'Basic realm="Super secret zone"');
local env = getEnv() or {};
local auth = string.decode64((env['Authorization'] or ""):sub(7));
local ,,user,pass = auth:find("([^:]+)%:([^:]+)")
if (not user or not pass) then
setReturnCode(401);
print("Please enter a username and a password!");
exit();
end
print("Hello, ", user, "who entered the password: ", pass )
?>
