What happened?
Cache always creates a filename (key) using the hostname. For this reason, cache does not work when using a route with limit a subdomain. For example, when the cache is enabled, it doesn't matter whether it is stored for xxx.domain.com or yyy.domain.com. It shows the same content in both addresses.
Steps to Reproduce
Expected Output
It is expected to produce content based on subdomains.
Cache must be compatible with subdomains.
