http - Why my iRules on BIG-IP F5 does not work? -


i want limit http::request rate 1 client, below irules:

when http_request {     if { [http::uri] == "/user/loginpub.jsp" } {         if { [clock seconds] == $cur_time } {             if { $req_count > 1 } {                 http::respond 501 content "request blocked."             }             incr req_count             return         }         set req_count 0         set cur_time [clock seconds]     } }

but when apply virtual-server, requests uri (/user/loginpub.jsp) reseted. chrome shows "connection reset".

why doesn't work? wrong ? thanks

this rule should not causing connection reset, suspect there else going on site. said, it’s not going want either. [clock seconds] never going equal $cur_time since didn’t assign value $cur_time before using it.

there’s example of rate limiting rule should able adapt on f5’s site:
