Formas de Django rompiendo en IE7

Question

Tengo un formulario web de dJango de un modelo con alguna comprobación de errores (campo de correo electrónico válido, etc.). Todo funciona bien en varios navegadores Opera, Camino, Netscape, Safari e IE (excepto IE7).

Todo lo que obtengo en IE7 es el mensaje 'Internet Explorer no puede mostrar la página web'. Si los formularios son válidos, los datos se escriben en la base de datos, así que creo que tiene algo que ver con la etapa de redireccionamiento.

He intentado varias cosas method = get y envío de formulario javascript pero nada parece detener IE7 que me da este error.

Cualquier ayuda sería apreciada.

confirmar que es la etapa de redirección que está causando el problema mediante la sustitución de

HttpResponseRedirect(url) 

con

HttpResponse('<!DOCTYPE html><html><head><title>title</title></head><body><a href="%(url)s">%(url)s</a></body></html>' % {'url':url}) 

Si esto no hace, entonces el problema está ocurriendo antes de la redirección. Si lo hace, entonces el problema puede ser la redirección, o puede ser la página redirigida. Clic en el enlace. Si la siguiente página se muestra correctamente, es casi seguro que el problema es la redirección. De lo contrario, el problema está en la página redireccionada.
