    Elsewhere in this group someone posted this link:
    net/?_a=knowledgebase&_j=questiondetails&_i=208

    A useful page.

    But what on earth is Gradwell doing? When I displayed the page I noticed
    there was some traffic outgoing from here, repeated every 20 seconds or
    so:

    SSL? Encryption? What was Gradwell phoning home about?

    I didn't click on anything on the page, just displayed it. As soon as I
    closed the page, the traffic stopped.

    Gradwell?

    noticed there was some traffic >outgoing from here, repeated every 20
    seconds or so:[Snip]


    I emailed Peter Gradwell direct, asking him what was going on. He
    explained that the phone-home traffic was to do with the Chat Now button
    on the page. So I then asked him for more details:

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    all by itself every 20 seconds
    - because it monitors whether we are online or not.
    Just usual cgi stuff, like refer values, browser type, length of time on
    page etc.

    cheers

    So now we know. "Just the usual cgi stuff." Yeah, right!

    I also know that I have no time for vendors who play sneaky underhand
    tricks like that. Gradwell is definitely off my list of potential
    candidates for VoIP service provider.

    Doesn't look underhand to me, just making sure the button on the page, that
    presumabaly shows if live support is avalable is avalable is showing the
    correct status!

    probably see)

    There's nothing wrong with the basic idea. But why use SSL? Despite
    Gradwell's "explanation", I have absolutely no idea what information
    they are phoning home.

    (A little while ago I was using another VoIP package -- Echolink -- and
    discovered that it too was phoning home -- in that case, the serial
    number of my hard disk. That was in clear, however, so easier to spot. I
    don't use that package any more).

  5. - we use SSL because our whole site uses SSL, and if we invoke non SSL
    requests on an SSL page, then the browser will complain - which confuses
    people.

    No it doesn't. I've just clicked on your home page (http://...) for
    example, and there's no SSL or phoning home there. Also, the original
    link that started this topic was http, not https.
    I think your web designer is confused. You need to think a little more
    about page design.

  7. This seems to be a lot of fuss about nothing.

    I haven't used Gradwell before, but they seem like an honest enough
    company. How many others companies do you know where the founder reads
    Usenet and answers posts?

    If they wanted to do something iffy, they could do so when the page was
    first requested. Your browser can't send anything back on future
    reloads that it couldn't have sent back the first time.

    Seems like too much information is overloading your brain

    god knows it doesn't take much...
    I think you're the one who's confused. You need to think a little more about
    whether a succesful VoIP player, is going to take any notice of a
    foaming-mouthed conspiracy theorist on Usenet.
