# Intercepting HTTP requests with a DelegatingHandler

**[Tim Deschryver](https://daily.dev/sources/timdeschryver)** · [@timdeschryver](https://daily.dev/timdeschryver) · 3 min read · 0 upvotes · 0 comments

## Summary

DelegatingHandler in ASP.NET provides a centralized way to intercept HTTP requests and responses, allowing common infrastructure logic (like adding authentication headers, logging, or error handling) to be written once and automatically applied to all requests made by a given HttpClient. The post covers implementation and DI registration using AddHttpMessageHandler, and highlights how this pattern keeps application code clean and avoids scattered, duplicated logic.
