title: Can I validate a file's size with flash and still normally upload it?
body: <p>Imagine you have a form that allows file upload. The file's size is limited to X MB. When we want to validate the file's size, we run into problems with Internet Explorer and it's security features.  </p>
  
  <p>We thought Flash might be a solution, and we'd like to check a file's size using it, and, if it passes our validation, allow it to be submitted along with the rest of the form. The thing is, all of the code snippets that use Flash to perform file validation, are using Flash to post the file upload. I'd like to be able to post the entire form at once, since my object depends on all of the params being received at once.</p>
  
  <p>A colleague of mine said the above scenario should be possible, but I think it's not. Are there other alternatives, or is creating/handling the post using entirely Flash the only one?</p>
