~~~Hi, I have set limited concurrent access, when over the limit, visitor will see error page like this

---

I tried at this setting
SetEnvIf Request_URI /app QS_ErrorPage=http://mytestserver.com/error.html

But NOT success, any other settings I can try, or my setting is wrong ?

Thanks

I wonder how our configuration looks like in detail. What's configured per server and what per location level?
And, you didn't use "/aoo" as the URI pattern, do you?
Do you really need dynamic error page mapping or have you tried to configure it statically using the QS_ErrorPage directive?

[Calvin Wong]

MY CONFIG IS VERY SIMPLE LIKE THIS:

QS_SrvMaxConn                   250
QS_SrvMaxConnPerIP              10
SetEnvIf Request_URI /app QS_ErrorPage=http://mytestserver.com/error.html

Anything wrong ? I am not familiar with Apache and firtime using mod_qos, hope you can help newbie and give some simple expample

Thank you very much

You can't configure an error page for directives denying on connection level (there is no response without a request).

Thanks,
when over the limit, redirect to customized error page
anyway to make this work ?

[Pascal Buchbinder]

You could redirect requests using QSRedirectIf based on thresholds you configure for the QSSrvConn and QSIPConn variables. But this won't be a hard "connection" limitation as you need to wait for the client sending a request.

Therefore the QSLocRequestLimit and QSClientEventRequestLimi directives together with QSErrorPage would be the most obvious solution.
