Subject Long process with ASP
Date Wed, 06 Aug 2003 13:54:04 GMT
Hi, my name is Julian Lisenberg, and I'm an ASP programmer from Argentina, South America (so
please understand that my English isn't perfect). I had the same problem that Landin Nikolay
(Apache::ASP List), and I come to the same conclusion that you did, because of the big scripttimeouts
that the multi-part process could handle.
 
But, after coding a really long process, I discovered something. When I close the client page
that is processing the ASP, the process keep processing à it does not finish as I supposed.
I have opened the DB after closing the client's page, and the information keeps growing. Why
is this happening? Is it good or is it bad? Do you know any way to stop a process like this?
Does this kind of process have something to do with multi-threads? 
 
Finally, I was able to handle this process with application variables, so I could start this
process, close the client page, and open it again and saw were it was. Is this safe?
 
Thank you for your time,
 
Julian Lisenberg
