Is it possible to make a background thread run all the time to do monitor job in asp.net?

[Nick]

hi,

I have a asp.net project. I want to start a thread in this project at
some point to do some operations on database.Is there a limitation on
this thread about how long it could run? Is it possible to make it run
all the time to do monitor job?

For me, looks like it works on my machine. But when I put it to the my
webhost, public it, it won't work. It did not run into the thread at
all. And It did not say any error about new thread or start thread
error. Just won't run into the thread proc. (I used the regular method
to start a new thread with c#. I works fine on my local machine.)

Thanks.
