I'd like to follow up on that. The last time I checked, ProxyErrorOverride was silent in the logs. A notice- or warning-level message when it intervenes would be helpful in many situations. The typical conversation around ProxyErrorOverride starts with "It's the error page of the proxy, so the proxy must have caused the error." That discussion could be cut short with a log message stating ~"ProxyErrorOverride applied after receiving status XXX from the backend." > The application could signal to httpd that its response has a user-friendly > body via a special header. I thought about this before. I think a more general, more flexible approach would be very helpful. In the end it boils down to something like rewrite rules on the response. You can to this with ModSecurity, but that is too late for ProxyErrorOverride AFAICT. Ahoj, Christian Folini -- Christian Folini - <christian.fol...@netnea.com>
