I have a python script that redirects the browser to a ZPT like this: return context.REQUEST.RESPONSE.redirect(request.URL1 + '/myPage') I woluld like to pass an argument to the ZPT that will be accessible through the 'options' property like this: <p tal:condition="options/errorMessage | nothing" tal:content="options/errorMessage">Error message</p> Is there a way to use the RESPONSE object to set the 'options' property before the redirect? Is the 'options' property user-accessible (writable) at all? Another related issue: how can I redirect to a ZPT passing all form properties from the current request like in the following pattern: HTML Form page -> action script that redirects -> Form handling page Thanks in advance. --Borislav
