set session variable using link
I have a page with two links: link1 and link2.
When the user click link1, then the session FOO should be set to 1.
When the user click link2, then the session FOO should be set to 2.
Is there a way to do this with data assist?
And is there a way to set the session value without showing the session variable value in the address bar of the browser? (i.e.: using form instead of links)?
TIA for any help.
