                    <button id="login" value="" type="submit" name="login"></button>
                </div>
            </div>
            </form>
        </div>
    </div>
</body>
</html>

On the login.html page, change this.

// change this line
<input type="hidden" name="dst" value="$(link-orig)" />
// to this
<input type="hidden" name="dst" value="http://www.google.com" />

now it give me
“error 404 - file not found”

and the website is -
www.myhotspotdnsname.com/www.google.com

what to change?

Thanks,

To choose different page shown after login, in login.html change:

to this line:

(you should correct the link to point to your server)

I guess I need to change it to -
http://www.google.com

and not just
http://www.google.com

now it’s work - thanks!
