Erhm, sorry, Samu, but this _is_ how ZPublisher works. It chucks all the
raw HTTP request stuff into REQUEST and lets you easily extract it.

For example, give a form such as

  <form action="Foo" method="post" enctype="multipart/form-data">
    <input type="text" name="Name" value="">
    <input type="submit">
  </form>

then the object Foo can consist of the following DTML:

  <dtml-var standard_html_header>
  Your name is: <dtml-var Name>
  <dtml-var standard_html_footer>

Here, REQUEST is implied because it's part of the namespace stack. Note
that REQUEST is pretty low in the namespace stack: It means that if
there is a folder or object called Name along the acquisition path, then
the above DTML will use that. So, a general, good rule of thumb is to
always reference REQUEST; thus it becomes:

  <dtml-var "REQUEST.Name">

or

  <dtml-var "REQUEST['Name']">

Here's a tidbit I think you'll appreciate: In your form target -- in
this case Foo -- or indeed in any DTML document or method, place the
following DTML:

  <dtml-var REQUEST>

This will render a HTMLized version of the current request's REQUEST
object.
