Unable to remove Accept header

[Ssaely]

I've been using reqwest and I've noticed that it sends the Accept header despite me not manually setting this header.

There also seems to be no way to remove this header as it is is stored in the ClientBuilder's config.

@Ssaely It's true that you can't delete the ACCEPT header, but you can replace its value in the ClientBuilder:

use reqwest::{Client,header::{HeaderMap,HeaderValue,ACCEPT}};

let mut headers = HeaderMap::new();
headers.insert(ACCEPT, HeaderValue::from_static("application/json"));
let client = Client::builder()
    .default_headers(headers)
    .build()?;

It's usually useful to set this header. If you're a Rust fan, think of it as adding type-checking to HTTP :-)
