Question

I am writing a library which writes something into the database for temporary use (use only once) and then gets removed (its strange, but there is a certain implementation necessary for this ). For this I am trying to execute a thread which writes in the data into the database, waits for the page to finish loading and then releases to finish executing, removing the record. I am not sure how to apprach this. One way is to make the thread sleep but then I am risking either not allowing enough time or the thread might still be running after the page has finished doing everything else. Is there a way to tie this into the page thread so I can release my thread right after it finishes? What are some, if any, approaches to something like this? Because this is a library I would much rather not have another programmer call a function at the end of his page code to remove the record; its messy and easily forgotten.

Unless you want to use threads for some other reason (i.e. educational) consider using Application events for that – you can listen AcquireRequestState and ReleaseRequestState or similar pair depending on your needs and perform your database operations. Check application lifecicle to see all events and order of them.
