Reading and terminating stream in HttpClient 4

问题

I'm reading large documents from which I only need top 5%, can I do the following with HttpClient 4?

1. Request the page (get or post)
2. Read response as a stream
3. Feed it into SAX-based HTML parser "on the fly"
4. When certain HTML tag is detected - terminate the stream

Please note that HttpClient v. 4 is required - I cannot use v. 3

Thanks to Ken from HttpClient mail list here's the answer

Use the HttpEntity#getContent() method, which returns an
java.io.InputStream, and pass that to your SAX-based HTML parser.

When you see the tag you need, terminate the request via invoking the HttpUriRequest#abort() method.
