You should see the data added on each submit.

If need be, give /usr/temp and /usr/temp/data a mode of 777. Change the field values in the HTML form to something different so you'll recognize them, and add a pause to the Perl script, say, 7 seconds: sleep(7);. Add the sleep statement somewhere between where the script grabs the data and where it writes it to the file. When you run the form now, you'll see a little hourglass or wristwatch or whatever your OS uses to tell you to park it for a minute. But forget that. You're in a hurry. Hammer on the submit button a couple or few times. Finally, you'll get the Thanks! screen. Meanwhile, your data file starts to grow.

The user is left with the impression that all that hammering on the submit button finally pushed the data through, but only one set. OK. We've clarified the problem. What do we do about it? << Back  Next >>
