HAProxy version:2.2.1  
I wanna capture tcp packet and make acl by captured tcp packet but now I’m trying to capture payload it doesn’t work.  
My configuration

```auto
frontend hts_frontend
    bind *:8400
    mode tcp
    maxconn 3000
    option tcplog
    log global
    timeout client 1m
    tcp-request inspect-delay 1s
    tcp-request content capture payload(0,192) len 1

```

I want to capture the 118th character same as screenshot and make acl if the character is 1 going to A backend server other character is going to B backend server
