Dynamic Client Creation extension

[Njeriiii]

There are a lot of ways to create client dynamically - for loop is a good case, another one could be code inside a web controller method that's executed on each request. Users sometimes create clients there, but should instead create a single instance and reuse it.
There could be 100 other ways to do it.
Even with a loop, one can create 10 clients, but if they are against different endpoints, it'd not be a problem.

Need to explore different cases and flag problematic ones
