Class not getting destroyed on Redirect

Steve Lutz

Hello,

I have a page that creates a class, and then on certain conditions,
redirects user to another page. The class has a Class_Terminate() function
that saves itself to a database. The class comes from an includes ASP file,
it isn't a COM object.

Here's my code outline (not actual code for brevity - in otherwords, there
may be syntax errors, but that's not the cause of the problem)

<!--#include file="myclass.asp">
<%
objClass = new cMyClass
cMyClass.variable = "Somethign"

if (somecondition) then
response.redirect("someotherpage.asp")
end if

%>
The problem I am having is that if the page does not redirect, cMyClass's
Class_Terminate function is run, however, if the redirect statement is run,
Class_Terminate doesn't get run.

Is this a known problem in ASP classic?

Try:

Set objClass = new cMyClass
cMyClass.variable = "Somethign"

if (somecondition) then
Set objClass=Nothing
response.redirect("someotherpage.asp")
end if

Hi, I guess I should clarify, I was trying to generalize the problem..

The object I'm using is going to be used globally through-out the site to
ensure user is logged in. To make future pages easier to code, the object
Class_initialize function reads cookies, and attempts to authenticate the
user. If unable to, then the user is redirected to an login page. Since it
is the class itself doing the redirect, then it isn't possible for the class
to destroy itself.

<!--#include file="myclass.asp">
<%
objClass = new cMyClass

' If I get here then the user is logged in.

%>

put the redirect into the include file outside of the class

'class definition here

Dim objClass
Set objClass = new cMyClass

if (objClass.mustredirect() ) then
Set objClass=Nothing
response.redirect("someotherpage.asp")
end if

Hi Mark,

Thanks for the assistance, but this isn't the functionality I need. I need
to write a foundation for the site so junior developers can concentrate on
UI issues and not the application. Oh.. but I guess I just thought of a
workaround:

The include file that has the object in it, actual creates an instance of
the object as well (outside of the class definition). So after I create it,
I'll just see if it needed to redirect...

Question though, are classes supposed get destroyed when a redirect happens?
Do they get destroyed by the Class_Terminate isn't called?

uh, Steve,

The work-around you came up with is what I was recommending.

As far a the class terminate on re-direction you might try a simpler
mechanism for determining if the terminate method fires or not. Possibly the
database access cannot take place once the page is out of scope. Try writing
out a flag to a file just to see if that is possible. I know that doesn't
resolve the actual issue you have but it may shed light on what is actually
happening.
