No.  See below.

OK, if I am guessing correctly from what you say above, this zone file
is for the domain "mydomain.com".  So you are asking "www.mydomain.com"
to be an alias for "www.web.mydomain.com".  BUT, nowhere do you define
the latter!

I would have thought you would want "www.mydomain.com" to be an alias
for "web.mydomain.com":

www		IN	CNAME	web

otherwise, you will need to define "www.web.mydomain.com":

www.web		IN	CNAME	web

or

www.web		IN	CNAME	1.0.0.1
