# Authentication Failure Handling in .NET
In my recent blog post titled ".NET Authentication and Authorization," I discussed the configuration and implementation of authentication and authorization in a .NET application. However, I failed to address an important aspect: handling authentication failures.
By default, the authentication configuration in .NET uses a cookie policy. When an authentication failure occurs, it responds with a 302 status code and redirects to the `/Account/Login` page. This poses a problem when the frontend and backend of the application are separated, as the redirect will not point to the correct address.
For instance, let's assume the frontend app is hosted at `localhost:8800` and the backend app at `localhost:9900`. If an authentication failure occurs during a frontend API request, the response will contain a 302 status code with the location set to `localhost:9900/Account/Login`. The frontend, using HTTP APIs like `fetch` or `Axios`, will automatically fol...--GPT 4
Rust - bytecodec Encoding and Decoding Library
This blog post discusses the use of the bytecodec library in Rust for encoding and decoding data. The author starts by explaining the need for a simple protocol to serialize objects into binary format for network transmission. Instead of using JSON, the author decides to create a custom protocol where each field is represented on a separate line. However, the author soon realizes that the implementation becomes messy and lacks abstraction.
The problem lies in the lack of a standardized approach to encoding and decoding. Although the `Peer` object only has three members, each member needs to be individually implemented for encoding and decoding. This lack of abstraction leads to inconsistent naming, implementation, and method usage, making the code difficult to manage.
To solve this problem, the author proposes the use of traits to provide a standardized approach to encoding and decoding. The bytecodec library offers the `Encode` and `De...--GPT 4
