How to enable the use GET, HEAD, POST, PUT, DELETE, PATCH requests on a Plesk for Windows Server

Question

How to enable the use of GET, HEAD, POST, PUT, DELETE, PATCH requests on a Plesk for Windows Server?

Answer

To enable these HTTP methods, follow the steps under each section:

I. Enable HTTP methods in IIS:

1. Connect to the Plesk server via RDP.

2. Launch Internet Information Service (IIS) Manager at Windows Start > All Programs > Windows Administrative Tools.

3. In IIS Manager, expand SERVERNAME > Sites > click on example.com > Handler Mappings (under IIS).

4. Find the handler which is used by the website and double-click on it.

   For example, if this is a PHP website, double-click on PHP-php.

5. Click Request Restrictions....

   
   
   
   

6. Switch to the Verbs tab.

7. Add required verbs in to the verbs field, for example:

   CONFIG_TEXT: GET,HEAD,POST,PUT,DELETE,PATCH

   
   
   
   

8. Click OK to apply the changes in both windows.

   Note: If you get the warning "The specified executable for the handler must be a .dll or .exe file", that means the path in the Executable (optional) field contains spaces. In this case, use double quotation marks to specify the executable, for example:
   "C:\Program Files (x86)\Plesk\Additional\PleskPHP74\php-cgi.exe"|-d siteId=10

II. Disable WebDAV handler for a domain as it conflicts with PHP/.NET Core handler

1. Log in to Plesk.

2. Open the domain's web.config file at Domains > example.com > File Manager.

3. Find the section<system.webServer>and add the following content under it:

   <system.webServer>
       <modules>
           <remove name="WebDAVModule" />
       </modules>
       <handlers>
           <remove name="WebDAV" />
       </handlers>

III. Adjust ModSecurity

In some cases, ModSecurity may block HTTP methods if a strict ruleset (e.g. OWASP, Comodo or a custom ruleset) is being used. In this case, switch to the Atomic Standard ModSecurity ruleset: go to Tools & Settings > Web Application Firewall (ModSecurity) > Settings > Atomic Standard > Click OK to apply the changes.
