    Detecting changes in (~static) web pages

    Just idly wondering whether anyone had used http://www.changedetection.com to detect changes in usually-static webpages, and how useful/reliable they found it? Does anyone know of a similarly- <img src=/S/free.gif border=0 alt=free width=30 height=15> service which checks more than once per day?

    Thanks!

    Hi BATcher,
    I've used Outposted from Xequte Software before. It's <img src=/S/free.gif border=0 alt=free width=30 height=15>!! And I haven't found any spam generating from this company's site.
    A snippet from their web site on Outposted:
    <hr>Give OutPosted a list of your favorite sites and whenever changes are detected the site is e-mailed to you. Unlike similar software, OutPosted does not send a link to the site, or a lame "Notification of Change" message, but the actual web page, fully formatted, as an email message.<hr>

    Thanks, Bob!

    I'll look at that, but it will depend on how often the test for a change takes place.

    I'm also looking at developing a BATch solution using the command-line utility WGET, which will download the current version of a web page which can be compared with the previous one - even the file size would be enough to detect a change (of some sort)...

    No problem BATcher, I believe Outposted will check a site(s) every minute if you so configure it. Worked well for me.
    Have fun.

    I'm not sure how WGET works. Does it capture the headers sent by the server? In the case of .html pages, you usually will get a "last modified" timestamp with a .html page. This may not be available with .asp, .php, etc.

    I like the Firefox addon Update Scanner 2.2.3 https://addons.mozilla.org/en-US/firefox/addon/3362 you con control the scan frequency and it renders the new page with the changes highlighted.
