Session_OnEnd does not DeleteFile()
I've got an ASP3 (IIS6) site, in which some scripts need to generate
temporary files in order to work. Now, the fact is: I would like those temporary files to be deleted when a user's session ends (even though i've got infinite hosting space, i feel it somewhat impolite to leave GB's of useless temp files ;-) ). The Session_OnEnd event, though, seems to have some problems in doing this: 1. I found in MSDN that it couldn't call Server.MapPath(). Not a big problem, I hardcoded the base path and everything should have worked well. 2. The FileSystemObject.DeleteFile() method, though, seems to suffer from the same problem: i get no error output on Session.Abandon() but the files are still there. Is there any workaround for this problem? Thanks in advance Andrea Azzini andrea azzini wrote:

There is no other solution. IWAM needs file-system permissions for that folder.

The email account listed in my From header is my spam trap, so I don't check it very often. You will get a quicker response by posting to the newsgroup. No way to get that. But I've found another solution... i'll use a BLOB in
the mysql database where i surely have all the access rights i need. Thanx anyway.

news:vblUd.53852$QG6.973817@twister2.libero.it... I didn't look at Aaron's link but if you cannot get it scheduled, I looked : This sounds really interesting, i had not thought about it... but, is there : any way to have a script run at an aribitrary time or should i just put it : into another (frequently accessed) page and let it check whether it's time : to run or not? : Remember i am on hosting so i can't do more than edit the files in my site's : directory... at it this way. My customer has a menu for administration. This is separate than maintenance. Administration has two functions. 1. Get orders 2. Cleanup Get orders will show a list of all order files and they can be viewed, printed and archived. Cleanup cleans up all temporary files in the orders file directory that are 3 days or older, based on a value in the config file. I inform them to run a cleanup at least once when getting orders. My shopping cart cleans up files when orders are complete and only leaves successful order files. I cannot determine if someone fails to complete a shopping experience but I can try to do cleanup with Session_OnEnd. I found several issues with that approach. So, I chose to just make a generic routine that cleans up the files. There are 2 files left if the order is not completed for each shopper. 50 shoppers = 100 files. They are single digit k byte XML files. 100 files would be less than 1mb. This is only for unprocessed orders and they are only created if someone leaves something in their shopping cart and either leaves the site, closes their browser or times out. I also didn't want to clean them automatically in case someone was having trouble and called support. This would give the support person something to look at so the order could be completed on the phone. For those who host their own sites, I can offer an automated cleanup, if desired. Nobody yet has requested this process be automatic since cleanup takes care of it and only takes seconds at the most.
