Reset IIS on ASP.NET site when an error occurres

i have an ASP.NET web site that on some very rare occasions has an error that causes a lot of requests to fail. the error is caught and logged in the OnError override of my base class for all pages so i know when the error occurred.

since this error is very rare i want to reset the iis when it occurres so the site will return to function normally.

my开发者_JAVA百科 question: on the OnError code below, how can i cause the IIS to reset? i can run iisreset or can cause the iis to crash using something like System.Environment.Exit(-1). what is there a preferred method to reset the iis?

    Protected Overrides Sub OnError(ByVal e As EventArgs)
        LogException(Server.GetLastError())
        MyBase.OnError(e)
    End Sub

1. To touch (modify) web.config (similar alternative is to touch/modify bin folder)
2. To ask AppDomain to unload (using HttpRuntime.UnloadAppDomain)

Check this article that discusses this approach.

I would also suggest you to consider period application pool recycling (possible from IIS configuration) as alternative. an
