I apologize if I've missed the answer to this -- I hope that I have so that I can finally address this issue on my site.
In DNN 2.1.2, after login the user would be returned to the same URL they left ... this was perfect for my site, as I display data dynamically using URL parms (grabbing a news article by its key value, for example). An unregistered user would see the teaser, login, and then return to that same article with the access they needed to see the full text.
Then I upgraded to 3.1.1
I've been bollixed ever since. Though the "<None Specified>" site configuration for Home page returns a user to the same tab after login, it loses the URL parms. Without retaining the URL parms the user is returned to errors after login, rather than the article detail. Meanwhile, having users redirected to the home page is inconvenient, requiring them to find the desired article again.
Any suggestions you can provide are appreciated - I scoured Snowcovered for module solutions and didn't find one, so I must be doing something wrong. I am using Friendly URL addresses, if that helps narrow my problem at all.
Thanks for your help.
