Execution order of HttpLimitReq, proxy_pass and rewrites

[j0nes2k]

Hello,

I have tried to rate limit a resource using HttpLimitReq that is passed
on to a backend Apache server. Now when I try to limit this resource,
nothing is blocked and all requests go through. When using static
resources, the limit_req works as expected. Here is my config: 

location /cgi-bin/test\.pl {	
	limit_req zone=one nodelay burst=3;
}

location /cgi-bin/ {
     proxy_pass         http://default_backend/cgi-bin/;
}

I think this might be related to the execution order or these modules.
Which of the commands limit_req and proxy_pass is evaluated first? How
can I limit the access to resources in a backend server?

Thank you for your help!

Best regards,
Jonas Kaufmann
