I have a strange effect that I see in one of my projects where I am setting
up header entries provided as a list derived from user settings. I am using
the code below that is supposed to delete old header entries, then collect
the ones to be applied and finally applies the entries. To my understanding,
this should only include the headers that I add in this respective call.
Instead, what happens is that the previous ones remain active and the ones I
append in further calls to that function are being added additionally. I was
following the example in: https://curl.se/libcurl/c/CURLOPT_HTTPHEADER.html
That sounds strange.
If you can extend the example code to reproduce the problem we can have a
closer look at it.
