<p>This is another example of a Lua server page, served by
<a href="https://github.com/civetweb/civetweb/">CivetWeb web server</a>.
</p><p>
The following features are available:
<ul>
<?
mg.write("<li>" .. _VERSION .. " server pages</li>")
if sqlite3 then
mg.write("<li>sqlite3 binding</li>")
end
if lfs then
mg.write("<li>lua file system</li>")
end
?>
</ul></p>
<p> Today is <? mg.write(os.date("%A")) ?></p>
<p> URI is <? mg.write(mg.request_info.uri) ?></p>
<p> URI is <?=mg.request_info.uri?></p>
<p>Database example:
<pre>
<?
-- Open database
local db = sqlite3.open('requests.db')
-- Note that the data base is located in the current working directory
-- of the process if no other path is given here.
-- Setup a trace callback, to show SQL statements we'll be executing.
-- db:trace(function(data, sql) mg.write('Executing: ', sql: '\n') end, nil)
-- Create a table if it is not created already
db:exec([[
CREATE TABLE IF NOT EXISTS requests (
id INTEGER PRIMARY KEY AUTOINCREMENT,
timestamp NOT NULL,
method NOT NULL,
uri NOT NULL,

-- Add entry about this request
local stmt = db:prepare(

stmt:step()
stmt:finalize()
-- Show all previous records

-- Close database
