Detecting changes on website

[Gordoni]

I would like to make script which detects changes on website.

#include <INet.au3>
Global $cipka = InetGetSize("")
WHile 1 
$cipka2 = InetGetSize("")
    If $cipka > $cipka2 Then
    MsgBox(4096,"", "ALERT.")
ElseIf $cipka < $cipka2 Then
    MsgBox(4096,"", "ALERT.")
    EndiF
Wend

This is my code and doesn't work . Any ideas?

InetGetSize requires a full URL

this will work

InetGetSize("http://www.cyberload.pl/test.txt")

this will not work

InetGetSize("www.cyberload.pl/test.txt")

If the page has text that changes, you can use this code to detect that.

#include <INet.au3>

Local $URL = "http://somesite.com/pagetocheck.html", _
    $Text = "Blah, blah blah blah", _
    $Source = _INetGetSource($URL)

If StringInStr($Source, $Text) = 0 Then
    ;; If $Text is different than what's defined..
    MsgBox(0, "", "Change!!")
EndIf

Thank you guys

Its also worth noting that the source of a webpage can change without there being any visual changes.

search your source code for 'salt' and if its present you might see what I mean, and you'll have to work aroung it.
