Private home page (6)
I believe the answer is:
inside
'private' is the definition.
(similar in meaning)
'home page' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'page' becomes 'side' (one side of paper).
'in'+'side'='INSIDE'
(Other definitions for inside that I've seen before include "Enid is (anag) - within" , "Middle" , "(Of information) from a confidential source" , "Inner surface" , "Not external, perhaps in prison" .)
