Nimbostratushow set connection rate limit on specific uri with iRule ?
hello
I use this iRule
when RULE_INIT {
#Allow 3 Requests every 1 Second
set static::maxRate 5
set static::windowSecs 1
}
when HTTP_REQUEST {
if {[HTTP::host] equals "host.com" and [string tolower [HTTP::uri]] contains "/favicon.ico"}
{
reject
}
elseif {[HTTP::host] equals "host.com" and [string tolower [HTTP::uri]] contains "/openapi/v0/identity/register" } {
set uri_limitervar [HTTP::uri]
set get_count [table key -count -subtable $uri_limitervar]
if { $get_count < $static::maxRate } {
incr get_count 1
table set -subtable $uri_limitervar $get_count $uri_limitervar indefinite $static::windowSecs
} else {HTTP::respond 503 content "<html><h2>You have exceeded the maximum number of requests per minute allowed... Try again later.</h2></html>"
#Drop the Connection afterwards
drop
}
}
elseif {[HTTP::host] equals "host.com" and [string tolower [HTTP::uri]] contains "/openapi" } {
HTTP::header replace "Host" "apim3.sdb247.com"
HTTP::header insert X-Forwarded-For [IP::remote_addr]
HTTP::header insert X-Geo-Country-Code [whereis [IP::client_addr] country ]
HTTP::header insert X-Geo-Country-Area [whereis [IP::client_addr] state ]
# SSL::disable serverside
pool Prd-NGNX_443
}
}
but after 10 or 5 minute all connection for this uri will drop.
and now what is the problem?
