*.mydomain.com.	IN	A	192.168.12.12

bind does not care about HTTP. BIND will point A records to your IP but
that's all.

Note that wildcard DNS has caveats, e.g. it only applies to otherwise
non-existent records, not to any existent, so if you e.g. define

abc.mydomain.com	MX	...
www.def.mydomain.com	A	...

then the *.mydomain.com will NOT apply to abc.mydomain.com
