問題文
The access log page warns that the place of the access log support in the routing matters, and it spells out what happens if the support is registered last of all. What does the page say happens then?
選択肢
- The support is reached twice, because the routing hands the request to the tail of the chain and then walks the chain a second time.
- The support writes a line with the returned number missing, because the reply has gone out by the time it runs.
- The support writes a line only for the requests that no handler claimed, because the rest end earlier in the chain.
- The support is never reached, because another service or handler will have finished the request before its turn arrives.
