[SOLVED] Flask change the server header

Flask change the server header

I've made a simple flask application:

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET / HTTP/1.1
host:google.be

HTTP/1.0 404 NOT FOUND
Content-Type: text/html
Content-Length: 233
Server: Werkzeug/0.9.6 Python/2.7.6
Date: Mon, 08 Dec 2014 19:15:43 GMT

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>404 Not Found</title>
<h1>Not Found</h1>
<p>The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.</p>
Connection closed by foreign host.

One of the things I would like the change is the server header which at the moment is set as Werkzeug/0.9.6 Python/2.7.6 to something my own chosing. But I can't seem to find anything in the documentation on how to do this.

Solution

You can use Flask's make_response method to add or modify headers.

from flask import make_response

@app.route('/index')
def index():
    resp = make_response("Hello, World!")
    resp.headers['server'] = 'ASD'
    return resp
