How to enable DELETE, PUT for PHP app at IIS?

Question

Although DELETE request works successfully locally, it does not work when I deploy my app to MS Azure.

Here is what I get in console when try to delete a record:

DELETE http://mywebsite.azurewebsites.net/api/subjects/1 405 (Method Not Allowed)

My app uses mySQL at cleardb

How to fix such a problem?

EDIT

My app is a PHP 5.5 app, here is what I tried to do in web.config to enable DELETE and PUT, but it didn't work:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
        <rules>
        <rule name="Imported Rule 1" stopProcessing="true">
        <match url="^(.*)$" ignoreCase="false" />
        <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        </conditions>
                        <action type="Rewrite" url="index.php?url={R:1}" appendQueryString="true" />
                </rule>
            </rules>
        </rewrite>

<validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="WebDAVModule" />
    </modules>
    <security>

        <verbs applyToWebDAV="false">
          <add verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS,XYZ" allowed="true" />
        </verbs>
      </requestFiltering>
    </security>

         <handlers>
<remove name="PHP55_via_FastCGI" />
  <add name="PHP55_via_FastCGI" path="*.php" verb="GET, PUT, POST, HEAD, OPTIONS, TRACE, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, UNLOCK" modules="FastCgiModule" scriptProcessor="D:\Program Files (x86)\PHP\v5.5\php-cgi.exe" resourceType="Either" requireAccess="Script" />

              <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
              <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />

Answer 1

I think PUT and DELETE are disabled in WebApi / IIS8 by default, which is what it looks like you are using. Quite a bit of discussion on this here.
