Why do I need the Redis cache for the public website? #6533

• ABP Framework version: v8.0.1
• UI Type: Blazor Server
• Database System: EF Core (SQL Server)
• Tiered (for MVC) or Auth Server Separated (for Angular): no

We have already made several ABP applications with Blazor Server (without Redis Cache). But never with the "Public Website" so far. Now we would like to integrate it and were surprised that the Redis cache is necessary here. We do not have a distributed / tiered application.

I know that this is a prerequisite for the CRM module.

I would be interested to know why the cache is absolutely necessary? What are the reasons for this? Does it have to do with the fact that the Blazor app and the public website share certain things?

I also have the question of how large the cache needs to be if I host the application on Azure... that costs extra money again...

Thanks, Adrian
