Where exactly in the form structure are locks set for a request?

In the structure of the lock form block for a request, it is usually fixed at the moment of processing form data, most often in methods responsible for validation or data submission. In Go, this can be implemented using mutexes (sync.Mutex) or other synchronization mechanisms, which are located inside the form structure or a related controller.

For example, if the form is represented by a structure with fields and methods, then a mutex can be declared as a field of the structure, and locking will occur in methods that modify the form's state or send a request:

import "sync"

type Form struct {
    mu sync.Mutex
    data map[string]string
}

func (f *Form) Submit() {
    f.mu.Lock()
    defer f.mu.Unlock()
    // request sending logic
}

Thus, the fixation of locks occurs inside the methods of the form structure, ensuring thread safety when working with request data.
