Does this site look broken?. Use the LitterTray web for test cases.

this will always set (or clear) a session attribute:

%IF{"1=1" then="" else="%SESSION_VARIABLE{"name" set="1"}%"}%

you can't use the variable to set a session attribute in an if-statement. i wanted to set or remove a session attribute, if an url-parameter is set or not but failed. later i realized that the condition isn't taken into account.


Correct. This is because variables are evaluated "inside-out-left-right", so the SESSION_VARIABLE is evaluated before the IF is evaluated.

Do this instead:

%SESSION_VARIABLE{"name" set="%IF{"defined urlparam" then="1" else="0"}%"}%

Discarded.
