I strongly recommend that you at least skim through the information on my page about how the ArduServer2 code was developed, but if you want just "the answer", here it is. At least here is the Teensy half of things. You use an ordinary web browser, e.g. Firefox, for the client. You can access an ArduServer over your LAN or across the internet.
I developed the following in November 2014, on a Windows 7 machine, with the Arduino environment 1.0.6, and Teenyduino (Teensy Loader) 1.20
You will have to change one line if you don't want to use port 80.
You will have to change the several lines with my URL (http://mon7nc...) if you want access across the internet. (Change the URL from my URL to your URL.)
You'll need to alter the LAN address line, if you haven't put your ArduServer on 192.168.0.240.
You may to change the line which sets the device's MAC. (You can use any number that isn't already used by something else on your LAN.)
If your LED is not on D5, and your phototransistor on A1, there will be other simple, single-line changes to make.
I have a Windows program which can run in an internet connected computer anywhere in the world, and keep an eye on the temperature where an ArduServer2 is. If the temperature falls below a level of your choosing, an alarm goes off.... the PC begins beeping. This is up and running, but not yet in a version for selling. If you want me to get the commercial version launched, write and say so, I'll see if I can get to it! Somehting similar could be written for ArduServer3

//There is a LOT of Bad Code in this... but only in respect of
// FWWBuf and related matters. Not really relevant to what I
// imagine brought you here: A demo of the basis for Home Automation,
// remote sensing, etc. with Arudino/Teensy over the internet.
//(Code will work in Teensy EXACTLY like this, and not much changed
// in an Arduino.
//MOVE TAKE TTURE READINGS UP, deal with putting READING, not marker "5.21" in FWW line

/* This code this derives from is HEAVILY based on the example
"WebServer" supplied with (at least) the Arduino environment 0022,
August 2011. Arduserver3 was an evolution of Arduserver2, which is
where the "WebServer" example was first used as a basis.
Arduserver3 was developed Nov 14 with...
Arduino software 1.0.6
Windows 7
A Teensy 3.1, with a Wiznet820io module.
You DON'T, in the environment described above, need the
w5100.cpp, w5100.h library files you may come across
if you search the web.
--------------
Arduserver3: A complete statement of What's Needed...
(at least I will TRY to make it complete)
Hardware & software envirinment: See above, plus...
Incorporated in this code:
include <SPI.h>, <Ethernet.h>: Using "just" the standard
library modules supplied with the 1.0.6 Arduino
environment.... but be aware: They MAY be altered during
the installation of Teensyduino. Which may be good for
the Teensy's needs, and either benign or helpful for
"real" Arduinos. I hope so, anyway! (The two includes
were part of Arduserver2, too, but I want to be clear
about What You Need.
Pins used....
By Wiz820io, as married to Teensy by shield from www.pjrc.com/
(Table copied from their site. The SD card is not used in
Arduserver3, but its pins might just as well be avioded.
The MCP1825 is a voltage regulator on the shield.

ALSO from the pjrc.com site...
"Some SD cards can be sensitive to SPI activity while
the Ethernet library is initilized before the SD library.
"For best compatiblity with all SD cards, these 3 lines
are recommended at the beginning of setup().
Pins 4 and 10 will be reconfigured as outputs by
the SD and Ethernet libraries. Making them input
pullup mode before initialization guarantees neither
device can respond to unintentional signals while
the other is initialized."
((Following HAS BEEN added to Arduserver3)))
void setup() {
pinMode(4, INPUT_PULLUP);
pinMode(10, INPUT_PULLUP);
delay(1); // allow time for both pins to reach 3.3V
(End "also from pjrc.com site")
Other pins used are as follows. The following means that
the LED (which users of the server can turn on and off)
should be on pin 7, etc. These assignments can be changed,
if you'd rather things were elsewhere.... just don't change
them TO a pin already in used by the Wiz820io (+SD card) shield
const byte bLEDpin=6;//The LED users of the web page can turn on and off
const byte bBeeperPin=7;//A local "beeper" (self oscillating) to tell those
near the server that it has been accessed
const byte bTturePin=5;//Pin used to connect a Dallas DS18B20 tture
sensor. This is optional, not "core" to what Arduserver does.)
const byte bAnInWatchLEDPin=0;//For photosensor that monitors the LED
the user can turn on and off. Reading on this confirms for remote
users that their actions had the desired effect
const byte bAnInWatchAmbientLightPin=0;//Not core to what Arduserver does.
=== Old documetation....
From the example "WebServer" supplied
with (at least) the Arduino environment 0022,
August 2011.... BEGIN (edited) QUOTE...
A simple web server that shows the value of the analog input pins.
using... in Arduserve2 an Arduino W5100 Ethernet shield,
in Arduserver3 a Wiznet820io
Circuit: (ARDUSERVER2!... see other for Arduserver3)
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
ADDED TO DEMO by TKB:
N.B.: May need changing from instance to instance...
IP addresses... LAN and internet URL (latter appears several places)
Port
Pin assignments
... added to demo continued...
A light sensor on (A0) looking at room's ambient light... not
central to function of demo, but needed, if text on served web
page to be valid
A light sensor on (A1), which an LED shines on when it is shining.
Probably best to wrap them together with opaque tape, sort
of a poor man's "opto-isolator"
An LED + resistor on pin designated by value in bLEDpin
A beeper on pin designated by bBeeperPin... not essential to demo
(Bring pin high to turn either on... "beeper" makes continual
whine while on.)
Also added a Dallas 1-Wire temperature sensing chip, DS18B20, on input 5.
The internal ID of YOUR temperature sensing chip will need entering
into the program if you want to use the same facility, and the
1-Wire reading code in this is VERY crude.. you may want to replace
it. It will only read a DS18B20, for instance.
** N.B. ** The signal line needs to be pulled up to 5v. through a
4k7 reisitor when working with the Teensy, a 3v3 device internally,
with 5v tolerant inputs. I was using my DS18B20 *not* "parasitically
powered", i.e. one pin to 5v, one pin to ground, the last pin Dallas
data pin. See http://sheepdogguides.com/dst9parasitic.htm for
more on the "parasitic power or not?" question, if you want it.

/*THE LETTER AT THE END OF THE DATE shows not,
which would be usual in my work, a later version
of something done earlier on the same day.
Instead, there are four versions of ArduServer2...
"a", "b", "c" and "d", identified by the last letter
of the version ID.
Version "21 Jan 12d" was best and (at this point) latest version
of ArduServer2 when development stalled. Was "finished".
Old-at-11/14 note:
KEEP THE VERSION ID TO 10 characters:
The page served is nearly "too full", and
the "ver" string is inserted into the HTML.
HISTORY:
Changes from Arduserver2, ver "21 Jan 12d" to create
Arduserver3. (I will TRY to keep this comprehensive!)
Arduserver3 was built from Arduserver2, taking ver
"21 Jan 12d" of Arduserver2 from http://arduserver.com/a5as2code.htm
on 13 Nov 14.
There are "messy bits" left over from earlier editions, but the idea
was to "prove" that the Teensy + WIZ820io were practically
"drop in replacements" for previous hardware.
In Arduserver, Arduserver2, and Arduserver3, you may well have
to make changes to the constants set up for ip[], mac[] and bPort
(These are similar to setting a static IP address for any device
you may want to put on your LAN.)
Where Arduserver2, and the OLD "official" server example had...
Server server(bPort); ... in the 1.0.6 "Server" example,
and for Arduserver3, we want...
EthernetServer server(bPort);
Similarly...
Client client = server.available
became
EthernetClient client = server.available
Some changes were made which are not documented here, such as
changing the title of the page from "Arduserver 2" to
"Arduserver 3". These were just details of my use of what
the Teensy+Wiz820io made possible, and I thought them too
distracting.
I WILL mention re-enabling all the code relating to the
Revolver Map. In my previous Arduserver, that had to be
sacrificed as I could not, in the previous environment,
have such a large page.
