Hello!
I'm dario, from italy!
I was looking to nginx because i need a reverse proxy that can filter request to my server (proxy is on another machine).
I need a proxy to filter web-service request like soap message (tcp-http-soap-xml).
The request body of http is a xml.
I want something like count the number of the tag inside the xml and filter is the number is> X.
Then i would like to change the value of X on the feedback of the server CPU load. (dynamic behaviour)
I don't know if nginx is what i need, but maybe you can suggest a solution, even if i have to create a plugin o something like this.

Thanks for your time!
