What should my readable secondary be in SQL AlwaysOn?
With an SQL AlwaysOn, I Set my readable secondary to read intent only. When I try to connect with parameter applicationintent=readonly my connection is established with the primary server. Your connection string likely doesn’t specify the database. It has to include the database name so that SQL Server can tell which routing list to use.
What happens if applicationintent does not specify readonly?
If it hasn’t specified ApplicationIntent=ReadOnly (or something similar), it will get directed to the primary. If it is all reads, your connection string likely doesn’t specify the database. It has to include the database name so that SQL Server can tell which routing list to use (your server could have multiple Availability Groups running on it).

Why are AlwaysOn availability groups used in SQL Server?
SQL Server AlwaysOn Availability Groups have become the most common High Availability technology used with SQL Server. This technology provides protection at the database group level, and it stores a separate copy of each databases on each server or node, which eliminates storage from being a single point of failure in the infrastructure.
