Hi,
thanks for ur reply.
My problem is, my code is like
#code code code
if REQUEST['usr_msg']:
do some operations.
#some code related to project
my program control loops with above " if condition".
REQUEST is in same context.
so once REQUEST stores 'usr_msg ' every time when it goes to "if
condition " , it performs that "do some operations"
Due to above reason i want to delete that "usr_msg" variable from REQUEST
But if you would really manage to delete this from REQUEST, you
would get an exception when trying to use it in the way above.
So, see Peters solution to your problem.
also i cannot put restriction on "usr_msg" ,because it comes from user
input, and user can give any text to that variable.
If thats some kind of filter chain you probably want to change
it to some private name space within request as you would be
comfortably getting by REQUEST.set('allmystuff',dict())
at the very beginning. You can actually look up form values
from REQUEST.form to distinguish between user input and
data from your program. If you just ask REQUEST, you get
some kind of stacking layers of name spaces where values get
looked up.
Please see the Zope book (online) for description of the API.

Actually you can't. (Not without writing a product in filesystem
and getting deep into zope). Why would you?
What you could do is to update one of the requests namespace to
give the variable a new value.

Re: [Zope] delete a variable from REQUEST
Just set it to None.
if REQUEST['usr_msg']:
do_something()
REQUEST.set('usr_msg', None)
Then, the next time the condition will be false.
