Hi,
it is my first time use twisted .
i want to use the a function pass a url then get the web page
the code as :

the getPage is definition in twisted.web.client

def getPage(url, contextFactory=None, *args, **kwargs):
    """Download a web page as a string.

    Download a page. Return a deferred, which will callback with a
    page (as a string) or errback with a description of the error.

    See HTTPClientFactory to see what extra args can be passed.
    """
    scheme, host, port, path = _parse(url)
    factory = HTTPClientFactory(url, *args, **kwargs)
    if scheme == 'https':
        from twisted.internet import ssl
        if contextFactory is None:
            contextFactory = ssl.ClientContextFactory()
        reactor.connectSSL(host, port, factory, contextFactory)
    else:
        reactor.connectTCP(host, port, factory)
    return factory.deferred        
--------------------------------------------------------------------------------   
Question:
for the  getPage function,if  use it to get 10000 page ,it would open/close
connection 10000 times,it is a very large cost。
So ,any body can give me some advice?creat a class inherit from HTTPPageGetter(as a protocol class)
or HTTPClientFactory?
