i am trying to start with http server. What i did is get http server example, add very simple main page with button and trying to response on POST requests. The issue i am having is that i cant do anything with too big uri/header. All i have found is this docs info.
https://docs.espressif.com/projects/esp ... tPc6size_t
I injected some logging to this function but it is never reached because server is responding with error 413 before.
