Invalid HTTP status code 405 in Chrome only

Question

I have a WCF service which saves a customer to a database and works as expected in Internet Explorer but not in Chrome (for that reason i will leave out the HTML/Json as it makes me think this is a web config issue but i can post if anyone likes).

In Chrome i get the error:

Failed to load resource: the server responded with a status of 405 (Method Not Allowed) Subscriber.htm:1 XMLHttpRequest cannot load http://example.com/MyService.svc/SaveCustomer. Invalid HTTP status code 405

My Web Config:

<system.web>
    <compilation debug="false" strict="false" explicit="true" targetFramework="4.0" />

        <add namespace="System.Runtime.Serialization" />

    <httpProtocol>
      <customHeaders>
        <!-- Enable Cross Domain AJAX calls -->
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type, Authorization, Accept, X-Requested-With" />
        <add name="Access-Control-Allow-Methods" value="OPTIONS, TRACE, GET, HEAD, POST, PUT" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>

So I've read a few articles and added relevant sections, removing WebDav but nothing seems to make a difference.

Right, i was going to delete this thread but thought that someone may come across this issue in future and to save them from a headache.

In my webconfig, i removed (otherwise you get an error)

<httpProtocol>
  <customHeaders>
    <!-- Enable Cross Domain AJAX calls -->
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Content-Type, Authorization, Accept, X-Requested-With" />
    <add name="Access-Control-Allow-Methods" value="OPTIONS, TRACE, GET, HEAD, POST, PUT" />
  </customHeaders>
</httpProtocol>

In my WCF web service i added a new Global.asax and added

Sub Application_BeginRequest(sender As Object, e As EventArgs)
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*")
    If HttpContext.Current.Request.HttpMethod = "OPTIONS" Then
        HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache")
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST")
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept")
        HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000")
        HttpContext.Current.Response.End()
    End If
End Sub

Hope this helps
