I've been experimenting with application.cfc
One of the things that i've seen on occasion in 6.1 is a "Session is
Invalid" error that users can get stuck in. I just saw a post over on
CF-Talk where someone recommended the following. The error seems to be
caused, at least according to the poster, by a discrepency or conflict
between J2EE sessions and CF sessions. It seems that if the CF session
expires and the underlying J2EE session still exists, CF throws a Session is
Invalid error at the cfapplication tag, which stops a new CF session from
being created. The net result is that the user is locked out of the
application (unless they move to another browser.)
<cftry>
<cfapplication
name="myApp"
sessionmanagement="Yes"
sessiontimeout="#CreateTimeSpan(0,0,20,0)#" />
<cfcatch type="Any">
<cfapplication
name="myApp"
sessionmanagement="Yes"
sessiontimeout="#CreateTimeSpan(0,0,0,0)#" />
</cfcatch>
</cftry>
I'm experimenting with translating the above to application.cfc like so:
<cfcomponent>
<cftry>
<cfset this.name = "myApp" />
<cfset this.sessionManagement = true />
<cfset this.sessionTimeout="#createtimespan(0,0,20,0)#" />
<cfcatch type="Any">
<cfset this.name = "myApp" />
<cfset this.sessionManagement = true />
<cfset this.sessionTimeout="#createtimespan(0,0,0,0)#" />
</cfcatch>
</cftry>
Comments? Opinions? Some workaround seems to be necessary, because my first
CFMX 7 client (human) has run into this error numerous times in the last 3
days as we get this app ready for launch, and he's understandably nervous.
