.NET 8–Http Logging

In .NET 7 and before the default request logging in ASP.NET Core is quite noisy, with multiple events emitted per request. That is one of the reasons why I use the Serilog.AspNetCore package.

By adding the following line to my ASP.NET Core application I can reduce the number of events to 1 per request.

The result looks like this in Seq:


Starting from .NET 8 the HTTP logging middleware has several new capabilities and we no longer need Serilog to achieve the same result.

By configuring the following 2 options, we could achieve this:

  • HttpLoggingFields.Duration: When enabled, this emits a new log at the end of the request/response measuring the total time in milliseconds taken for processing. This has been added to the HttpLoggingFields.All set.
  • HttpLoggingOptions.CombineLogs: When enabled, the middleware will consolidate all of its enabled logs for a request/response into one log at the end. This includes the request, request body, response, response body, and duration.

Here is a code snippet:

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
