I need to get user details before hitting the SharePoint Server page.
User hitting sharepoint page(https://spxy) then I redirect to https://spxy/_layouts/TestHandler.ashx via httpmodule.
I need to get IE User logged in Name in the http handler page.
Example:
XYZ Domain -- Test User -- John
ABC Domain -- Test User -- Alex
Contoso Domain -- Test User -- Tom
I just logged in windows login as Administrator, If I login in the IE using john then I need to his domain name and user name.
