How to test seesion expired

[jiecoldfusion]

<cfif IsDefined("Session.accounts_pk") and IsDefined("Session.org_pk")>
... some code
</cfif>

after seesion expired, above the "if statement" can not block process. and
coldfusion debugger tell error happens inside cfif block, (undefine seesion
variable "Session.accounts_pk" )

Can someone help me? Is that something wrong with fuction Isdefine()?

Thank you1

did you try to use ParameterExists(url.module)?

[jiecoldfusion]

ParameterExists doesn't work too!

Are you sure there's not something else happening? Try this:

<cfif IsDefined("Session.accounts_pk") >
<cfoutput>#Session.accounts_pk#</cfoutput>
</cfif>

And see if you still get an error. I've never had any problems with this.

[jiecoldfusion]

I try this before
(<cfif IsDefined("Session.accounts_pk") >
<cfoutput>#Session.accounts_pk#</cfoutput>
</cfif>
)

but it always keep saying that accounts_pk is undefine.

right now I use this for temp solution

<CFPARAM name="Session.accounts_pk" DEFAULT="FALSE">
<cfif #Session.accounts_pk# IS "FALSE">
</cfif>
So far, it works.

do you have any idea

Thank you for the advice,

If you define your session variables inside Application.cfm using cfparam with
a default value then you can simply test the variable for that default value to
see if the session has expired.

ie. <cfparam name="session.UserID" default="0">

Assuming session.UserID normally contains a non-zero value, it will reset to
zero at any point where a page loads and the session has expired..

cheers.

Yes,
<cfparam name="session.UserID" default="0">

Assuming session.UserID normally contains a non-zero value, it will reset to
zero at any point where a page loads and the session has expired..


above works.

Thank you!
