I have two different MVC applications. They are both using cookieless session states and both use this line to determine the application's root:
var root = '@Url.Content("~/")';
For some reason one application recognizes the cookieless parameter and provides a proper root url containing the cookie parameter (Something like: /(S(03lyoc2mzcq5cyqqqzgritk2))/). The other application just has the root url as /.
I have found a work around for the application that only provides /:
var root = '@Url.Action("Index", "Home")';
The application that properly provides the cookieless parameter combines both webforms and MVC. Any ideas on where my inconsistency might be?
After some research and testing it was the version of MVC that made the difference. It appears that in MVC 4, the cookie parameter will be included, however, in MVC 5 the cookie is no longer added to the url.
If someone has a more detailed answer as to why this feature was removed I'd be happy to accept it as the answer. I have a feeling it's because Microsoft isn't wanting to support cookieless anymore, but I have no proof to support that. This may be a clue... https://stackoverflow.com/a/21652454/386856
