First of all, you should write where have you found this question.

Anyway:



when you are using setHeader you are deleting the old contents of the header, and you are puting into it a new value.
when you are using addHeader you are NOT deleting old contents, you just add a new value to this header.

So the real question is:
If you have a Header with multiple values (as occurs after multiple calls to addHeader),
does setHeader replace ALL the existing values.

Good question.

the spec is clear about setHeader "the values are cleared and replaced with the new value"

therefore all values will be cleared
