Right, with Firefox the 'view source' really gives an empty source. I tried with MSIE before. 

When I test with IIS/.Net after hitting the button the browser is waiting for the response: waitcursor, "Waiting for localhost" in the statusbar, and the most important the page remains in the browser.

Testing with Apache/XSP/Mono an empty page loads in with Firefox or an empty page with that header loads in with MSIE.

I captured the traffic with ethereal and I found that you are right both IIS/.Net and Apache/XSP/Mono sends a response when hitting the button.

IIS/.Net's response:

    HTTP/1.1 200 OK\r\n
    Server: Microsoft-IIS/5.1\r\n
    Date: Wed, 25 Jan 2006 08:14:27 GMT\r\n
    X-Powered-By: ASP.NET\r\n
    X-AspNet-Version: 1.1.4322\r\n
    Cache-Control: private\r\n
    Content-Type: text/html; charset=iso-8859-2\r\n
    Content-Length: 1293\r\n
    \r\n

Apache/XSP/Mono's response:

    HTTP/1.1 200 OK\r\n
    Date: Wed, 25 Jan 2006 08:01:08 GMT\r\n
    Server: Apache/2.0.50 (Linux/SUSE)\r\n
    Content-Length: 0\r\n
    Cache-Control: private\r\n
    Keep-Alive: timeout=15, max=99\r\n
    Connection: Keep-Alive\r\n
    Content-Type: text/html; charset=iso-8859-2\r\n
    \r\n

And there is an interesting difference: the Content-Length field! IIS/.Net does the following: sends the HTTP headers as it was a normal response to a GET or POST request but sends no content and I think the missing content is what the browser is waiting for. :-)

I attached the captured traffic as text files. Please have a look at Frame 584 and Frame 995 in net.txt and recognize that two responses are the same except second one has no content. Then have a look at Frame 1331 and Frame 1603 in mono.txt and recognize that in Frame 1603 Content-Length is 0 and of course there is no content.

Now the question is what does this Content-Length stuff? IIS or .Net?

I tested this under MS and got the same results as with mono. The details are on the bug report.
