#yield scrapy.Request('http://icanhazip.com/', callback=self.is_tor_and_privoxy_used)
def parse(self, response):
page = response.url.split("/")[-2]
filename = 'quotes-%s.html' % page
with open(filename, 'wb') as f:
f.write(response.body)
print('\n\nSpider: Start')
print('Is proxy in response.meta?: ', response.meta)
print ("user_agent is: ",response.request.headers['User-Agent'])

self.log('Saved file --- %s' % filename)
def is_tor_and_privoxy_used(self, response):
