How to redisplay results?

saidbakr

Suppose,
User had used the application to get final results. Now if the user wants to retreive results which he obtained from a previous session. What are things and techinques I should to keep in minde and implement it inside the application to do that.
to give a specific example:
Suppose a simple application inwhich adding to numbers and display the result in bold and any color then,
User A11
Add 2 + 8 to get 10 in bold and red color---Sesion 1
User A11 (use the program again)
Add 12 + 5 to get 17 in bold and green color---Sesion2
Now user A11 wants to use the application to retreive the sesion2

Note ofcourse this's a very simple example and may be done so easy, but I need the way or style to do this if we have a complex application inwhich many forms and database connectivity to get results from it.

Let me mix up some more 🙂
How about the user has 3 browsers open at the same time and does 3 different calculations at the same time. Then he closes all the browsers and then opens a new browser and trys to go back. Which way back should he go? You question is trickier than you might suspect...

Now.. session data are destroyed when the user closes all the browsers he/she opens to a page. So you'd definitely have to use a database or write information on files.

I think your worst problem is not how to cache data and show them back... but how does the server react on extreme situations.

I would use a database and log the times of the user's actions. If the user wishes to go back I would recall the record with the latest time in the DB.

Yes, Let we say, I want some thing like this, to save the result page to display it again if the user wants it. I don't want to use the database.
Is XML is usefull for this or a simple text file is better?
I need more sugestions, if examples or code snippets available, this will be so helpful
