Why do my web forms lose data when I hit the back button? |

The assumption here is that when they go back to the form, the data (or most of it) they entered will still be there, so they can just correct the necessary fields and re-submit. Sometimes, though, the data is "missing" - the form is empty when the user goes back. I'm not sure of all the causes, but one thing I found is that if you do javascript validation of the form using an "onsubmit" event in the <form> tag, the problem occurs. To work around this, I call my validation routine from the submit button - using a "onclick" event. This may not work in all cases, but it did in mine. Have your own Tech-bit to contribute?
