In order to update the context.Response.Headers, you first need to understand the context in which you’re working. As you haven’t provided the specific context or environment, I’ll provide a general explanation and examples for different scenarios:

  1. ASP.NET Web API (C#): If you’re working with ASP.NET Web API, you can update the response headers through the HttpResponseMessage object returned by the action method in your controller. Here’s an example of how to do it:
using System.Net.Http;
using System.Web.Http;

public class MyController : ApiController
    public HttpResponseMessage Get()
        // Your logic here...

        // Create an instance of HttpResponseMessage
        HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, "Your response content");

        // Update the response headers
        response.Headers.Add("Custom-Header", "Value");

        return response;
  1. Node.js (Express.js): In a Node.js application with Express.js framework, you can update the response headers using the set method on the response object. Here’s an example:
const express = require('express');
const app = express();

app.get('/', (req, res) => {
  // Your logic here...

  // Update the response headers
  res.set('Custom-Header', 'Value');

  res.send('Your response content');

app.listen(3000, () => {
  console.log('Server started on http://localhost:3000');

Python (Flask): For a Python application with Flask framework, you can update the response headers using the headers attribute of the response object. Here’s an example:

from flask import Flask, jsonify

app = Flask(__name__)

def index():
    # Your logic here...

    # Create a response using jsonify or a custom response
    response = jsonify(message="Your response content")

    # Update the response headers
    response.headers['Custom-Header'] = 'Value'

    return response

if __name__ == '__main__':

These are just a few examples for different frameworks, and the actual implementation might vary based on the specific context and technologies you’re using. Please provide more information about your use case or environment if you need more specific guidance.
