yea... i tried the below options. Nothg seems working.
I have given the required credentials using web_set_user. I have made Yes the "Enable Integrated Authentication". I have also tried the "WinInet replay instead of sockets" and alternately web_set_sockets_option also. In IE -> Internet Options--> Advanced tab, checked the enable integration authentication option
and a Observation. The same flow works fine in VuGen 9.52 with same settings.
