Can't HTTP POST to ISAPI DLL!

External Since: Sep 04, 2003 Posts: 4

I have an ISAPI extension written in C++, running under IIS 6. I can
use the GET method to invoke it just fine, but the POST method fails.
I've tried playing with every configuration that I could find, but the
server keeps returning error 501. If I telnet to the server and try
the POST command manually, the HTML response contains the error
message

Bad request (Invalid Verb)

The permissions are wide open; anonymous access is allowed, scripts
and executable are allowed, the extensions are all enabled. I can GET,
but not POST.

In fact I can try a POST method with any URI whatsoever; I
consistently get that error.

Is post listed as a verb within the properties of the extension? Right click the site in question -> properties -> home directory ->
configuration button -> mappings. Double-click your extension and you will see if there are any verb limitations.

Thank you. I hope this information is helpful.
