python sys.stdout.write（）重定向

Question

i am redirecting a proxy server to my script which checks the URL, User-Agents etc and based on the checks it returns the user to specified URL.

now if i send a GET request back to the client it works, but it display only text version of the site with no css/images, this is part of the code which sends the request back to the client..

if l.startswith('User-Agent:') and ('Safari' in l):

    new = "http://www.yahoo.com"
    new_get = "GET" + " " + str(new) + " " + "HTTP/1.1" + "Status: 302" + "\r\n\r\n"
    sys.stdout.write(new_get)
    sys.stdout.flush()

i have tried to set

new = "302:http://www.yahoo.com"

but does not work either...

any ideas??

UPDATED:

if l.startswith('User-Agent:') and ('Safari' in l):

    new = "http://www.yahoo.com"
    new_get = "GET" + " " + str(new) + " " + "HTTP/1.1" + "Status: 302" + "\r\n\r\n"
    uopen = urllib2.urlopen("http://www.yahoo.com")
    sys.stdout.write(uopen.read())
    sys.stdout.flush()

tried with urllib2 and its takes a lot of time for the browser to render the page..but same results..no images/css..

Answer 1

If you want to redirect the client:

new_url = 'http://www.yahoo.com/'

print 'Status:', '302 Found'
print 'Location:', new_url
print

If instead you want to serve something directly to the client:

from shutil import copyfileobj
from sys import stdout
from urllib2 import urlopen

http_message = urlopen("http://www.yahoo.com")
copyfileobj(http_message, stdout)

Why are you doing all this by hand? The Python standard library contains modules such as urllib2 and httplib , and even SimpleHTTPServer to help you with tasks like these.
