Remove/Rewrite HTTP header 'Server: TwistedWeb'

There is some way to remove HTTP Header 'Server: TwistedWeb/13.1.0' from responses from a Twisted based web application?

I know this is an old question, but if you would like to remove the server http header. I am talking about the

request.setHeader('Server', 'SomeServer')

This is set by Twisted Web automagically if you don't specify a value. You can remove it by using the inner Headers class. For example,

request.responseHeaders.removeHeader('Server')

This will remove the Server Http Header.

You can rewrite any header by calling the request.setHeader method.

class RootPage(Resource):
    def getChild(self, name, request):
        request.setHeader('server', 'MyVeryOwnServer/1.0')
        return OtherResource(name)

The change applies to any resources on your site; you could put it in your Site class. You want that 404 or 500 errors would also return correct header; so you should set it as earlier as possible but not before it is set by twisted itself (in order to overwrite it):

#!/usr/bin/env python
import sys
from twisted.web import server, resource
from twisted.internet import reactor
from twisted.python import log

class Site(server.Site):
    def getResourceFor(self, request):
        request.setHeader('server', 'Server/1.9E377')
        return server.Site.getResourceFor(self, request)

# example from http://twistedmatrix.com/
class HelloResource(resource.Resource):
    isLeaf = True
    numberRequests = 0

    def render_GET(self, request):
        self.numberRequests += 1
        request.setHeader("content-type", "text/plain")
        return "I am request #" + str(self.numberRequests) + "\n"

log.startLogging(sys.stderr)
reactor.listenTCP(8080, Site(HelloResource()))
reactor.run()

Default Server http header is specified in t.w.server.version.
