Name on web for an aperitif (8)

I believe the answer is:

dubonnet

'for an aperitif' is the definition.
(I've seen this before)

'name on web' is the wordplay.
'name' becomes 'dub' (as in dubbing someone with a particular name).
'web' becomes 'net' (synonyms).
'dub'+'on'+'net'='DUBONNET'

(Another definition for dubonnet that I've seen is " Tub on end (anag) - aperitif".)

I've seen this clue in The Sunday Times and The Times.
