Re: [Webware-discuss] del from Session?

[slightly off-topic warning....]

Thanks. This does beg a more abstract question of why nobody else has found 
the need to delete from session. This makes me worried that I'm missing a 
better technique.

As an example, I have a PSP snippet form. The code that handles the form 
POST expects to see some variables in the current session -- for example, a 
page to redirect to on a processing error. When this code is finished, I 
want to "clean up," and remove the session key/value pair. I could pass 
this parameter as a hidden value in the form, but this seems less 
efficient, and open to abuse (since it exposes some inner workings to the 
client).

Is there a better way of handling this?

Thanks,
-- David
