'Http request stuck in the IIS webserver post authentication
We are having an IIS hosted web service and randomly some incoming requests get stuck post authentication. I have added some logging in the code but the call is not reaching the corresponding application code. Here is the sample call failing.
http://localhost/FlighterPhx/api/AbConfigOperations/GetABConfigBondFile&env=1&abConfigId=147114584.
In Http Authentication, the first call returns 401 and then the caller presents the Authorization information but the second call is not hitting the application code. Here is the entry in IIS logs:
2019-11-11 17:32:24 ::1 POST /FlighterPhx/api/AbConfigOperations/GetABConfigBondFile env=1&abConfigId=147114584 80 - ::1 - - 401 2 5 0
In a successful scenario there will be response code of 200 as shown below.
2019-11-11 05:34:42 ::1 POST /FlighterPhx/api/AbConfigOperations/GetABConfigBondFile env=1&abConfigId=147070852 80 - ::1 - - 401 2 5 0
2019-11-11 05:34:46 ::1 POST /FlighterPhx/api/AbConfigOperations/GetLatestABConfigId env=2&lineId=AdsFLN9 80 PHX\_toolsa ::1 - - 200 0 0 4734
Has any one faced this issue and what is the fix. Please help.
