Hello there;

IT' there any posibility session can collide or mixed into another session(s), means two o more users logged with his own credentials and running differents scenarios ( mortgage application ) can see data from another logged user (?), we developed a web site ( .net/SQL ) and everything is going well so far , but I have a complain from other users ( three so far ) that they have seeing another data or data scenarios belonged to other user (?) . We have been tryed to replicate the problem but evrything is normal so far, Please anyone can tell me if this is posible. I will appreciatted any help or comments related to this.
Thank you very much.

It would be "nearly" impossible to have two users running from different
clients (PC) heads on with one another. Simply there are 2 separate/distinct
sessions owned by these 2 users. Assume that you use Form Authentication.
User A reads a record (tRecord), your form will cache it with:

HttpContext.Current.Session["UserA"]=myRecord;

At a later time, user A comes back (same session), your form retrieves the
cached record with:

myRecord=(tRecord)HttpContext.Current.Session["UserA"];

With this assumption above, I do not think it is possible.

JHON;

Thank you for your reply. I was able to replicate the problem, and I am im[presed with the outcome. What realy happen is the following:

in the page load I have:

Sub page load()

if Not Page.IsPostBack then

function_a(Context.item("Object"))
Cache.Insert("MyDataSet1") = Context.item("Object")

else

function_a( Cache("MyDataSet1") ) 'event

end if

end Sub

When the page is post back due to an event the function_a will pass the Cache from another Session already happened in the server(?). Please let me know you though about it, I am really lost with this(?)
Thank you for your time

Ariel.
