# You can make Scrapy send HTTP/1.1 requests by overriding the Scrapy HTTP Client Factory, with the following (undocumented) setting:
# 
#     DOWNLOADER_HTTPCLIENTFACTORY = 'myproject.downloader.HTTPClientFactory'

from scrapy.core.downloader.webclient import ScrapyHTTPClientFactory, ScrapyHTTPPageGetter

class PageGetter(ScrapyHTTPPageGetter):

    def sendCommand(self, command, path):
        self.transport.write('%s %s HTTP/1.1
' % (command, path))

class HTTPClientFactory(ScrapyHTTPClientFactory):

     protocol = PageGetter
