Browse timer

[michelis]

I know about the problems and mi idea are to minimize it.
I have a browse which is refreshed every 9 seconds, but... it is needed in a certain period of time, lets say from 10 to 17hrs.
I know I cant stop the page from the client side, but.
What if I, at 17hs, delete all the sessions, forcing the user to loggin again.

1st Question:
-If the user do nothing, the client browser will continue sending requests to the server, the question is: having all the sessions deleted at 17, will the server respond?

Then, if the user realized it was logged out and loggin again I can set the timer to 0 and the browse will not refresh till 10hr when I again logged out all sessions
If the user logs in between 10 and 17 I set the timer to 9 secs,
If the user logs in between 17 and 10 I set the timer to 0 secs, disabling it.

2nd Question
-Can I use the browse filter to make the browse empty and modify the "No records found" message to tell the user it must logged in again?

3rd Question
-Any quick way of delete all sessions?

THanks

Hi Alberto,

Deleting all the sessions sounds like a fairly drastic method. If the browse you are refreshing was "required login" then it _might_ work, but it sounds like a terrible hack.

Here's another approach;
set the timer field on the browse to a variable, say loc:timer.
right click on the procedure, and see where loc:timer is used.
Then just before that embed something like;

If clock() < 8 * 360000 or clock() > 17 * 360000
  loc:timer = 0
else
  loc:timer = 6000
end

Capiche?
Cheers

Thanks Bruce, may be I´m confused.
I know your idea will work for a client requesting the browse, if it request the browse from 10 to 17 it has the timer and if not... not... but..
As I understand the browse refreshed only the data part but no the entire page.
Will it work with a client that has the browse open and refreshing and the time is changing from 16:59 to 17?, will the timer change for an opened browse?
And if I set the timer to 0 then it will never referesh, then the timer will never be activated again.
THanks

yes the timer will change for an opened browse.

yes, it won't _start_ again at 8am by itself. Perhaps between 17:00 and 8am you could just increase the time as much as possible, so it still polls just really really slowly.
