I want to get the logged in user inside Sharepoint to pass by parameter in a link inside the web part "Page Viewer".
In our company we need to integrate our pages in SharePoint, and when a user logs into SharePoint, the page viewer send the link ex:
The client needs to only login once. If his login in SharePoint is not necessary to login again in our pages, so the link will send what user is trying to access and no need to login again. Is this possible?
