Why should there be only one instance of HTTPClient?

Read tutorials on using httpClient(HttpClient API by Apache), it said that we should have only one instance of HttpClient. So Below are my doubts..

  1. Why is it so?
  2. Can I have two HttpClient on different threads.?

Because your HttpClient instance holds session data like cookies, credentials and so on. Even if you only use one single HttpClient instance, you're able to use multiple connections if you use a thread safe connection manager:

Technically, it is possible to use multiple instances in parallel, but then don't mix them up and use them independently!
