WebDAV is a set of extensions to Hypertext Transfer Protocol (HTTP) that provides the standard for editing and file management between computers on the Internet. This protocol allows users to perform remote basic file operations via the web, such as copying, moving, deleting, and so on. In IIS 7.0, WebDAV is a standalone extension module that needs to be downloaded separately, and WebDAV will be integrated in IIS 7.5, but WebDAV has clicked on Put,delete. So the RESTful service deployed on IIS 7.5 (WCF Data service,wcf Rest service,asp.net Web api,asp.net MVC) is tragic, and HTTP Error occurs when a put request is sent 405.0– Method not allowed error, the workaround is also very simple, add the following settings in the Web. config:
<system.webServer> <modules> <remove name=" </modules> " HTTP Error 405.0-method not allowed workaround for put operation of rest service on IIS7.5
