Is there a defined way to cancel an upstream proxy request from within the ::revproxy::upstream filter?
This is the case I can't quite see a way forward with.. GET /folder1/page.html when requested via port 443 we would want to reply via fastpath delivery with no proxying. when via port 8443 we would want to proxy this upstream. So I need to add a filter on /folder1 to deal with the 8443 case: ns_register_filter preauth GET /folder1* ::revproxy::upstream -target https://${server1} -url_rewrite_callback upstream_url_rewrite However, I can't see how we can cancel the ::upstream request from within when on port 443 and let the request fall through to fastpath delivery. I can simulate this case* by doing the fastpath return using ns_returnfile within the upstream_url_write callback and returning "" as the url... but this feels like a bit of an abuse of the proc - since I'm not rewriting the URL, I'm replying to the request.
