Using Zope 2.10.8 I'd like to let an access rule trigger a 301 'moved permanently' redirect. I created an external method to raise the exception, which almost does the trick except for the fact that it generates a 302 Moved Temporarily status code. from zExceptions import Redirect def myDispatcher(self, url): raise Redirect(url) Tried request.setStatus(301) both in my access rule and the external method, but this effectively disables the redirect. Also tried modifying my external method similar to request.response.redirect() as follows. Still no luck. from zExceptions import Redirect def myDispatcher(self, url, status, lock): raise Redirect(url, status, lock) I finally traced it to HTTPResponse.py starting around line 763-790 the 302 status seems to be hardcoded. How would I go about changing this? I'd rather not hack directly in the Zope code... self.setStatus(t) if self.status >= 300 and self.status < 400: if isinstance(v, str) and absuri_match(v) is not None: if self.status == 300: self.setStatus(302) self.setHeader('location', v) tb = None # just one path covered return self elif isinstance(v, Redirect): # death to string exceptions! if self.status == 300: self.setStatus(302) self.setHeader('location', v.args[0]) self.setBody('') tb = None return self else: try: l, b = v if (isinstance(l, str) and absuri_match(l) is not None): if self.status == 300: self.setStatus(302) self.setHeader('location', l) self.setBody(b) tb = None # one more patch covered return self except: pass # tb is not cleared in this case Norbert
