Change Cache Lifetime

I would like there to be a way to configure cache lifetime either globally or per connection / drive.

For blocks which was read at least once. It will be removed after 3600 seconds.
For blocks which was not read, It will be removed after 10800 seconds.

For some instances, these settings are WAY to long.

I also need this function, too.
RaiDrive has this function why Netdrive cannot have it and set up the limited size and lifetime for cache?
These restristions should be removed.

Dear Customer,

Thank you for using NetDrive.

We will discuss this with develop team.
