I observed that a duplicate request was sent 60 seconds following the first request, yet the browser's devtool displays only a single request

Question

I use axios to perform the request, here is an example of my codes:

const abort = new AbortController()
const res = await axios.get('/rl/dev/network/status', { signal: abort.signal })
// ...

Sometimes the backend will take more than 60 seconds to respond, and I can see a duplicate request was sent in wireshark

No.	Time	Source	Destination	Protocol	Length	Info
26	2.530103	192.168.20.10	192.168.20.1	HTTP	448	GET /rl/dev/network/status HTTP/1.1
526	62.468953	192.168.20.10	192.168.20.1	HTTP	448	GET /rl/dev/network/status HTTP/1.1

But in the F12 devtool only display the first request.

Where does the second request come from?

Thanks for answering, and I am not an English native speaker, forgive me if there are any wrong grammar in my sentences

Looking for how to avoid the duplicate request
