I've put this question on SO and the question was closed as not a real question
. So I read the FAQ, it says -
not a real question
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
How can they say it cannot be reasonably answered when the question already has 5 answers?
If it couldn't be answered, then how come it has 5 answers.
Question - Why do some questions which do get answers are closed as unreal?
PS: same problem here - How does Facebook do it? Directories or 404 custom error?
