Why are multiple App_Offline.htm files appearing in Recycle Bin

Question

I'm not duly concerned but can anyone suggest why since installing Visual Studio 2008 Service Pack 1 I keep finding multiple App_Offline.htm files in my recycle bin.

I suspect it's something to do with Visual Studio taking local websites off-line whilst it runs an automated process and then immediately deleting the files (moving them to the recycle bin). This doesn't seem very efficient thought and I'd like to make it stop if I can!

I haven't yet restored any of them to see where they came from, I've just been deleting them but I will the next one as I'm curious which is why I asked this question.

Thanks

Answer 1

App_Offline.htm is an indicator file that will bring down any web site. I'm assuming that you are doing Publish Website?

During publish, the target website will be brought down (by adding the App_Offline.htm), the required files copied over, and the App_Offline.htm is then deleted to get the website back up.

This is all I could find on the subject. Unfortunately it's also speculative.
