I am using WebAPI PUT and DELETE methods to perform actions from my website via AJAX using jQuery. My server is Windows Server 2008 R2 with Plesk installed. POST and GET requests work just fine, but PUT and DELETE fail. I was originally getting a 401 Unauthorized response when I first deployed my site to the server. I then performed some actions and it turned into 405 Method not allowed . I am now at a point where I'm receiving an Internal Server error: Handler “ExtensionlessUrlHandler-Integrated-4.0” has a bad module “ManagedPipelineHandler” in its module list Now, there are lots of posts

I downloaded a PHP script written using CodeIgniter. when I run it from the localhost, on going to the admin folder, it shows localhost again.

I read here that this might be due to a wrong code in the .htaccess file. This is my present .htaccess file RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.+)/$ $1
