I am working with a website running on IIS8.5 and I am seeing a set of requests with what I will call "WS" request headers showing up in the serverVariables collection as follows:
HTTP_WSHOST HTTP_WSIP HTTP_WS_IP HTTP_WS_AUTH HTTP_WS_VER HTTP_X_WS_VER HTTP_X_WS_EP_VER HTTP_X_WS_AUTH HTTP_X_WS_TSP_PROTOCOL_VERSION
I have done some searching, and all I can come up with is that
HTTP_WSIP are used by DomainTools crawler, and that in general, they might be related to WebSockets.
What are these headers commonly used for, and where might I find specs for each?
