I have a website that has a feedback form (run through a cgi script) that requires you to confirm your details beforeyou can submit it. e.g. fill out form [submit] > details come back for you to confirm [submit] > thank-you page. I have had problems with it not work at times and I wondered if I could automatically configure a cron job to do the form process once a day, at say 8am. If the company didn't get a mail one day they would know that there was a problem with the script or the server. Is this at all possible?
Not a problem. Create a script that calls the site via html, one line like this: http://www.yourdomain.com/script.cgi?name=something&telephone=something (replacing the variables and values with whatever's in your form). Then call that file as a cron job. Note - it may not work exactly that way, but that should be very close to what you need to do.
Better yet though, you need to make sure that the form just works all the time. What's with the downtime?
