Throttling requests in .NET Core web applications

Last year I worked on a team migrating a large application to ASP.NET Core from ASP.NET MVC 5. Among our goals we wanted to make the site use responsive layout, become “future-proofed” on a technology stack, and clean-up a bunch of legacy cruft. Our initial launch did not go smoothly and we reverted to the previous site to make changes. In the process we learned some “gotchas”.  Today I’m going to discuss one of those and how we addressed it. We’ll learn about throttling requests in .NET Core web applications.

Cookie management in DotNetCore web applications

For those of us used to cookies in traditional ASP.NET the switch to ASP.NET Core might leave us scratching our heads. In the old system we were able to directly add and remove cookies from both the request and response objects (for better or worse). This might have led to us writing and overwriting the same cookie multiple times during a request as different portions of code affected it. DotNetCore has changed the game and that’s a good thing, trust me. Today we’re going to learn a technique for cookie management in DotNetCore web applications.
