Accepted Answer

I just had the same problem with an old ASMX service (this has nothing to do with Fiddler). Solution:

You are calling your web service using the SOAP protocol. I'm guessing that the URL you use to call it is:

```
http://yourserver/service.asmx/methodOfService
```

However, this URL must be used when you do a simple GET or POST to your service (when using AJAX for instance). When using SOAP, you must use this URL:

```
http://yourserver/service.asmx
```

No method name, because it is included in the SOAP body.
