You see 3 (!) selected requests. I cannot select only one of them. If I click either, all three are selected. Further, only the first one has a status code icon (200 in this case), the others seem to have neither size nor type.
I assume this is some modern extension of the HTTP standard that allows multiple requests per connection.
However, this causes a big chunk of trouble if you want to debug things: the right panel is always showing the details of the first request. In the example above I have not found a way to inspect the (selected) POST request with all its data as well as the returned data for all three requests.
Can you please explain to me
- What causes the combination of the requests?
- How can I inspect the details of the different requests if possible at all?
