- The user does something that fails, due to server-side problems, and you wish to inform the user of this problem so it can be fixed.
- You redirect to a page with a URL something like /error.php?message=Something+has+gone+wrong.+Please+fix+it+and+try+again
- The user fixes the error on the server, and (since staring at the location bar isn’t a whole lot of fun) simply hits ‘reload’ in their browser.
- This causes much wailing and gnashing of teeth, as the problem apparently persists.
I’ll give phpMyAdmin partial credit for at least HTML escaping their errors, but… the stupid, it BURNS!
