I need to implement a limit number of connections to the URL's by mask (^/url/) not per one second, but per 10 seconds to 3. Is it possible with mod_qos? Can you give an example of config?
And one more question, does the mod_qos changes HTTP headers sent to Apache, like nginx write client IP address to X-Real-IP or X-Forwarded-For?
SetEnvIf Request_URI ^/url/ LimitMe
QS_EventLimitCount LimitMe 10 3
mod_qos may set headers using http://opensource.adnovum.ch/mod_qos/#QS_SetReqHeader
but you might also want to have a look at those resources:
