Making a request to an ActiveStorage resource fails occasionally #666
Description
Use-case
We're using Apartment alongside ActiveStorage.
In our S3 server, we have created a bucket for every tenant in our application.
Since ActiveStorage can hold only one bucket globally, we're switching the ActiveStorage bucket for every request.
The problem
When a request from one tenant is being served and a new request from another tenant comes in, the bucket held by ActiveStorage gets switched to that of the new tenant.
Now if the first tenant request is trying to access a resource in ActiveStorage, it results in a failure since request is being made with incorrect bucket name
Current workaround
A fallback mechanism to check if the generated ActiveStorage URL is valid. If it's invalid, change the bucket name held by ActiveStorage to that of the current tenant and make a new request

Kindly let us know if there's a better way of solving this problem
