Is it possible to see what rest calls a page makes when I visit it? Like if I go to google drive, can I see what calls my browser is making to their web servers? If so how? Would something like Wireshark be used in this case? Is there something higher level than that?
In Chrome Ctrl + Shift + I then click network. You can view all network traffic or filter it. AJAX requests generally show up under XHR (XmlHttpRequest) unless the website is using JSONP - in that case they would appear under Scripts.
