session object

[Otto]

Hello,
When I programmed with ASP we use the session object to swap data between the different web sides.What are the disadvantages of using the javascript session object instead of the post method.

Thank you in advance
Otto

Hi Otto.
I simulate the way PHP use sessions with a file. You can create a cookie with the name of the user and a string with the name of the file.
This file is a dbf placed in a folder with some columns a one row for every string you want to use and its value.
With some functions you can create a session, write it, read it, control if is alive and delete it if is a lot of time that is not used or closed
by a logout from the program.
There is some code to write but is working in the same way PHP does.

Hello Massimo,
I am using javascript session object and this is working perfectly.
Only - as nobody seems to use it - I do not know if I will face problems with these objects.
Development is much easier as with the post method and also speed is better.
Best regards
Otto

Hello,
I found good documentation for this here:
https://javascript.info/localstorage

The limit is 2mb+, depends on the browser.
Best regards,
