Don't have a hostgator account? you can get one by using this coupon link to claim your hosting under $4.00.
I contact support asking to find a way to do this from Parallels and they told me there is no way to do that. They can reset it for me when I wish to. Well, that doesn't work for me. I am not going to sit and wait 13 min in the chat window to get an agent on the line and ask them to please reset the application pool for my website.
If you are a developer you probably already know this work around.
Edit the web.config via the web management panel in Parallels or FTP the updated web.config via the ftp and the application pool should reset automatically. But you don't have experience you can easily do these easy steps from the Hostgator Hosting Panel for Windows.
Follow these Steps:
1) Login to Hostgator Parallels Panel Web Interface
2) Under the Websites & Domains, location your website and find the ASP.NET Settings Link
4) Save the changes by clicking on the OK button.
