Review Comment:
If I were to update the User-Agent separately for each append call, it would
require removing the existing User-Agent header and then updating it with a new
value. This process can be resource-intensive. On the other hand, if I perform
this modification only in one specific scenario, it would help minimize the
overall cost.
