In my case scenario, I had to proxy requests in IIS, because a website was moved from web server A to B, and the DNS wasn’t updated yet. All HTTP requests for the moved website are handled in IIS’ Default Web Site; that’s the wildcard host, and the original host no longer existed there.

Continue readingSet IIS Application Pool recycle defaults to Specific Times, not Regular Time Interval
By default, an IIS application pool (or “AppPool”) recycles on a regular time interval of 1740 minutes, or 29 hours. One reason for this time interval is that application pools don’t recycle at the same moment every day (every day at 07.00 for example).
