We are passing additional data to the server, which can affect performance.Our database engine is a potential bottleneck and might slow the overall experience down.There are a few downsides to this approach that developers should consider:

#Asp.net core private cache code

The code here is a starting point, but anyone can adapt it to their specific needs and technology stack. This post saw two approaches with Entity Framework Core and ASP.NET Core to reduce the chances of processing the same request twice. It’s always best practice to write your applications to account for idempotency. With the middleware registered, we get the same behavior across all forms with an input element with the name IdempotentToken. Using System using using using ContactForm.Models using using using using Microsoft.EntityFrameworkCore using namespace ContactForm.Pages Let’s take a look at our Message that we should only process once. In this case, we’ll be using Entity Framework Core and the unique constraint available on an index.

The first approach is to build idempotency into our resources. Ok, so how do we do that? Implementing ASP.NET Core Idempotency By Resource As requests come in, we will verify the token against the storage mechanism to ensure we haven’t seen it before. This token will then be sent to our server and saved to a storage mechanism. Since we’re dealing with web applications, each form will generate a globally unique token when the browser loads the UI.

We need to send an Idempotency token with every request that can cause a state change. So how do we make these non-idempotent methods idempotent-like? Making Calls Idempotent (In Theory) The later methods tend to mutate state, whether creating a new resource, updating an existing one, or deleting it entirely. Non-idempotent methods include POST, PUT, PATCH, and DELETE. The HTTP protocol has idempotency methods built into the specification, with GET, OPTIONS, and HEAD all generally used for reading operations. Exact requests can have harmless side-effects like sending a duplicate communication or can cause the stressful situation of withdrawing funds numerous times from an individual’s bank account. We have described a situation where a user may be double-clicking a form’s submit button, initiating multiple identical web requests. Originating from mathematics, the term idempotent is jargon for saying, “we can apply this operation multiple times and still receive the same outcome”. This post will show a straightforward server-side technique to reduce, if not eliminate, a user’s duplicate requests while still keeping everyone, including us, happy in the process. Still, the double-click can wreak havoc on unsuspecting web developers who assume all users will click once to submit forms. OS designers built Double-clicks into the UX language of all desktop operating systems. These torchbearers of the desktop have in their fingers the impulsive need to double-click every button.

Every successful web application inevitably gets more users, and in that crowd of users, there is an individual who enthusiastically carries the torch of desktop apps in their heart.
