read html source on requiring user-login website

[lvtrycld]

Hi. I'm now trying to read html source code on the website. I could use other targets website via Data socket(http://digital.ni.com/public.nsf/allkb/89171CEC879A70A3862572950057ACC6), but one webpage which is required user-login(such as facebook) can not access and returns error 1181. Could you someone help me to read the html source via LabVIEW? 

I can use LV 2015/16

There's a standard way of including a user ID & password in a URL.
