Using a stick table keyed using the `base32` fetch (or possibly using a str key and the `path` fetch) and then using the `table_conn_cur` fetch should provide the necessary information.

Could lua be a solution.
Hey Aleks,
I'm not sure Lua would be the right solution for your situation, counting stuff
is tricky.
Hm so you mean that lua could be a performance bottleneck for youtube scale ?
As I haven't used lua in haproxy or nginx I have no experience how it behaves
on high
traffic sites.
I thought to use something like this but "proc" wide
function action(txn)
-- Get source IP
local clientip = txn.f:src()
local url = txn.sf:path_beg("/MY_URL")
save_in_global_hash(clientip+url)
end
and query this save_in_global_hash with a service.
However, I think Redis has INCR, you you can store per URL counters and maybe (just maybe)
use Lua action in HAProxy to write to Redis.
Obviously, you'd need to look out for performance, added latency etc, but it
would be a start.
You can then access Redis outside of the HAProxy context and observe the
counters.
Maybe the stick tables could also be a solution because I use it already for
limiting access.
```
#
https://www.haproxy.com/blog/application-layer-ddos-attack-protection-with-haproxy/
http-request track-sc0 src table per_ip_rates
```
# table: per_ip_rates, type: ip, size:1048576, used:3918
0x7f3c58fa9620: key= use=0 exp=597470 http_req_rate(1)=1
0x7f3c4d299960: key= use=0 exp=588433 http_req_rate(1)=2
0x7f3c50cc8830: key= use=0 exp=241004 http_req_rate(1)=0
0x7f3c5c6b3eb0: key= use=0 exp=586046 http_req_rate(1)=1
...
```
Can i add there a URL part like path_beg("/MYURL")
Just my 2c, hope it helps you (like you helped many people on this list)
Thank you for your input.
Best regards,

Count uniq Client ips
Hi. I have a quite tricky requirement and hope to get some input for a efficient solution. I use a haproyx in front of a streaming server. The access log, in json format, writes out the http request to syslog which is this plugin https://github.com/influxdata/telegraf/tree/release-1.14/plugins/inputs/syslog Now I tried with https://github.com/influxdata/telegraf/tree/release-1.14/plugins/processors/dedup to get unique IP's but that's quite unprecise. I though maybe the peers could help me when I yust add the client IP with the URL but I'm not sure if I can query the peers store in a efficient way. The target is to know how much concurrent IP's request the a specific URL. Could lua be a solution. Thanks for any ideas. Best regards Aleks
