How to customize HttpClientRequester with Default Headers?

How do I add a Header to a configuration using Proxy? Every time I try to add Header, the proxy stops working.

With this code the proxy works:

_handler = new HttpClientHandler() { Proxy = new WebProxy("127.0.0.1", 8888), UseProxy = true, }; _config = Configuration.Default.WithRequesters(_handler).WithJs().WithDefaultLoader().WithDefaultCookies();

If you really want to change the agent for HttpClientRequester I would explicitly use it (with a HttpClient instance).

var handler = new HttpClientHandler
{
  Proxy = new WebProxy("127.0.0.1", 8888),   
  UseProxy = true,
  UseCookies = false,
  AllowAutoRedirect = false,
};
var client = new HttpClient(handler);
client.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0");
var requester = new HttpClientRequester(client);
var config = Configuration.Default
  .With(requester)
  .WithJs()
  .WithDefaultLoader()
  .WithTemporaryCookies();

Hint: if you load AngleSharp.Io anyway, then also use the much better / advanced cookie container from it.

Hope that helps!

@FlorianRappl, again thank you for your time and fast & depth reply.

Using reliply.org is very cool thing, thank you for showing it! Doing something would have been my next move. Impossible solve problems without certainties.

So now it’s clear, the server (in my case google.com) is simply ignoring the Accept-Language headers. I’m posting same query string by hand with a Chrome setted to en-US and results are different. When I use AngleSharp I don’t know why but Google understand that the request is made from Italy (where I live).

Thanks very much for your help, it was very useful. Beyond that it’s no longer due to AngleSharp (which I’m starting really to love)…

Have a nice day!
