MVC Controller State Managment

[Kunal Mandloi]

I am working on Webhooks Concept. Since Webhooks act like an trigger. It will be firing an event like Update or Insert takes place. Its a MVC application and I have two Controller Home and Webhook Controller. I am passing argument through Query String on Home controller. I have tried Session,TempData, Cookies for passing variable from home to Webhooks HttpContext.Session.SetString("UserName", Request.Query["UserName"].ToString());

and getting session value on webhook controller

HttpContext.Session.GetString("UserName");

Also tried the same for TempData

Issue is On webbooks Controller its coming null.

I need to store parameter (User Name ,password) and reused the same for database related operation

Kindly guide

Session and TempData both rely on cookies to identify the requesting browser. They have a limited life-span, so data you store in them won't hang around forever. If the data isn't available in the web-hook request, that means either the session has timed out between the initial request and the hook request; or the hook request was made from a different process than the initial request, or using a tool which doesn't store the cookies you set. You will need to find a different solution. Since you haven't provided any details of what you're actually trying to do, we can't offer any suggestions. NB: Storing credentials in memory is not a good idea.
