Hello,

From many days am facing a strange problem with my dotnetnuke websites after login,  for example if i login to the website with (www.mywebsite.com)  and if i try to remove (www) and access website (mywebsite.com) the user will be not logged in since i was loged in from (www.mywebsite.com)  and same for viseversa. and i have to loged again from (mywebsite.com) 

i think browser cache is not understanding that www.mywebsite.com and mywebsite.com are both same.

does any one know the issue.  waiting for reply.

Thanks

Hello Michael,

Thanks for your reply, I try to add http alias in portal settings both (www.mywebsite.com and mywebsite.com), but unfortunately this one is not working, i will try to configure the webserver.

but i just want to know if this problem is from Dotnetnuke itself or am i only facing this problem. 

Thanks

You want both the www and non www alias set in the portal settings. Set your default alias to the www version. You can select Redirect as the SiteAlias mapping mode. I haven't tried this myself, as I usually use URL Master from ifinity.
