I have two shared hosting accounts, each with limited storage space: HostingAccountA with 'PrimaryDomainA', and HostingAccountB with 'PrimaryDomainB'. A negligible amount of storage is being used directly by these primary domains.
If I'd like to create many subdomains of a third domain, 'AddonDomain', but the total required storage space is greater than what is available in a single hosting account -- is it possible to split the deployment of these multiple subdomains across more than a single hosting account?
Specifically, I'd like to add this same domain as an add-on domain in both HostingAccountA and HostingAccountB, and then somehow have it appear as if (in the end, maybe through a combination of CNAME- and/or 301-redirections?):
- HostingAccountA host subdomains: 'sub1.AddonDomain', 'sub2.AddonDomain', and 'sub3.AddonDomain'
- HostingAccountB host subdomains: 'sub4.AddonDomain', 'sub5.AddonDomain', and 'sub6.AddonDomain'
I realize that the nameservers for the 'AddonDomain' can only point to one of the hosting accounts, but not both. Thus it would seem that in HostingAccountB, subdomains 4, 5, and 6 would have to be created as subdomains of, say, 'PrimaryDomainB'.
Thus my question now becomes: is it possible -- perhaps via some mix of CNAME- and/or 301-redirections -- to have subdomains 'sub4.PrimaryDomainB', 'sub5.PrimaryDomainB', and 'sub6.PrimaryDomainB' appear to the end-user as 'sub4.AddonDomain', 'sub5.AddonDomain', and 'sub6.AddonDomain' (respectively), despite the fact that the nameservers for 'AddonDomain' are pointing to HostingAccountA (where 'AddonDomain' has already been defined as an add-on domain)?
