[mod_python] Trouble fetching POST arguments

Point whatever form you are using at:

  http://dscpl.user.openhosting.com/~grahamd/testing/details.py

Eg:

<form action="http://dscpl.user.openhosting.com/~grahamd/testing/details.py" method="post">
       <div>
        Handle:
        <input type="text" name="handle" maxlength="32"/>

        Password:
        <input type="password" name="password" maxlength="32"/>
        <input type="submit" name="login" value="Log in!"/>
       </div>
</form>

That URL will display various details about the request and for me at
least for a post form, yields something for req.read(). As an example,
try:

  http://dscpl.user.openhosting.com/~grahamd/testing/form.html

You can see my code for generating this at:

  http://dscpl.user.openhosting.com/~grahamd/testing/form-html.txt
  http://dscpl.user.openhosting.com/~grahamd/testing/details-html.txt
  http://dscpl.user.openhosting.com/~grahamd/testing/details-py.txt

I'll leave this up for a while, but will take it down at some point.

Hope this helps.
