I have a web administration page that allows changing of website stuff like CSS styles, banners, images, page titles, etc. Currently, I store page inputs in a class, then into a session variable, just so the administrator can see the page before actually saving it to the file system. I'm running into a problem where the administrator has two admin pages opened in their browser and working on them concurrently, say tab1 and tab2. Since I'm storing the page inputs into a single session variable called (MyClass)Session["PageInputs"], the last opened page (tab2) overwrites tab1's page inputs in that session variable. You can imagine going back and forth from tab to tab can cause corruption and unintended data being saved to the wrong page with this methodology.
I'm trying to come up with a way where instead of storing the page inputs into a single session, each page has the page inputs stored. This way I can open multiple pages and work on them currently. Is there a way to store a class to the Page? I couldn't find a viewstate for the "Page" class. Maybe there's another way to store a class per opened page and work on them concurrently?
