[GitHub] [trafficserver] masaori335 commented on issue #7603: background_fill is broken with HTTP/1.1

   I found the background fill works on HTTP/1.1 over TCP with the default config, but it stops filling cache if I set `CONFIG proxy.config.http.allow_half_open INT 0`. 
   
   For HTTP/1.1, `ua_txn->allow_half_open()` is the knob of killing tunnel (background fill) or not.
   - HTTP/1.1 over TCP: configured by the `proxy.config.http.allow_half_open`
   - HTTP/1.1 over TLS: it always returns false
