Does the concept of shared space exist in the seven cow space

  java, question

If I define a public space, then I define three subspaces: 1, 2, 3,
A picture of a.jpg was uploaded in the space public. I call the domain name of subspace and hash of picture through api, for example, the domain name of space 1 to get the data of a.jpg, can I get it?

Seven cows do not have the concept of shared space. According to your requirement description, it can be realized by binding different domain names directly to the same space. Similar to binding and to public space, both domain names can access a.jpg in public space.
