Enable GET, POST and Discovery Web page in ASMX Web Services

HTTP GET and POST are disabled by default in ASMX Web services. This shows how to enable them.

<protocols>
<add name="HttpSoap"/>
<add name="HttpPost"/>
<add name="HttpGet"/>
<add name="HttpPostLocalhost"/>
      <!-- Documentation enables the documentation/test pages -->
<add name="Documentation"/>
</protocols>

The above web.config entry enables SOAP, POST, GET, Localhost POST, and the "Documentation" (Discovery web page) to remote callers.
