第一次用http protocol, 不太熟，想问一下，我写的是client side, 如果我需要两个
thread， thread1 is just doing regular basis GET request and read the
response in a while loop. Thread2 needs to send GET request once and keep
the connection open and read the response stream continuously.(别问为什么，
不是我design的) Do I need two HttpClient instances? Because I'm afraid if I
only create one HttpClient, it will reuse the connection, then thread1 will
be blocked by thread2 since it never ends reading the data. If I create two
HttpClient

If I were you, I will use two instances of HttpClient.
what you need be aware of depends on the data you are going to
send and receive, I guess
in short, be careful of the stuffs need be synchronized

I
will
two

thanks, I'll try when the backend is ready. Data synchronization should not
be a concern so far, I only worry about sending/receiving data through
separate threads will interfere each other.
So can I assume that each HttpClient will establish one http connection?

I don't see why you can't use MultiThreadedConnectionManager with
different configurations.

not

Ok, I see some sample code like the following. So if I do this and use one
instance of httpClient for both threads, after both threads sends GET
requests, one thread is reading responds, the other one won't be blocked?
releasing the connection in one thread will not affect other threads?
public void createHttpClient() {
connectionManager = new MultiThreadedHttpConnectionManager();
final HttpConnectionManagerParams cmp = connectionManager.getParams();
cmp.setStaleCheckingEnabled(staleCheckingEnab

I think this looks fine. You'll have to try it yourself though.
