Suggestion: Trigger Event via webconsole

[Martin]

Hello,

I would like to have a feedback process from the actions in my app to mod_qos. But currently I seem to be only able to block or limit a user [1], but not just to increase the LimitCount for a given event or the BlockCount.

And thanks a lot for this module, it saved me today. I wish I had started using it earlier.

So, instead of a "limit" or "unlimit" action, you would like to set the counter to a particular value, right?

like
http://your.server.name/qos/console?address=194.31.217.21&action=setlimit&event=QS_Limit&value=1234

Either this, and/or just a simple http://your.server.name/qos/console?address=194.31.217.21&action=inclimit&event=QS_Limit to increase by 1. Actually I would prefer a simple increase, as it avoids race conditions. (like in Memcache, APC, Xcache etc.)

It would also be nice for situations, where you have distributed backends. Lets say, a visitor posts a comment, you can always report this action to a single server, thus detecting comment spam faster.

I already tried modifying the source in qos_handler_console, just was not sure which value limit_time should be or if I am doing it right.

} else if(strcasecmp(cmd, "liminc") == 0) {
        if(eventLimitConf) {
          (*e)->limit[limitTableIndex].limit++;
          if((*e)->limit[limitTableIndex].limit == 1) {
            (*e)->limit[limitTableIndex].limit_time = ???;
          }
      }
    }

I've committed the change (it will be part of mod_qos 11.8)

Thank you for sharing your thoughts and ideas.
