URL Rewrite with Form Validations

[George Christman]

Hi, I'm doing some URL rewriting and I just discovered a new issue. I have
the following page rewritten to a new URL. "/sell/buildlisting/sell-car"
with "sell-car" being the context param and I'm rewriting the URL to
"/sell-car". When a form.error occures and the page reloads, it returns
"sell/buildlisting.form". How do I get the page to return "/sell-car.form"?
