You get whatever the webserver chooses to serve at that URI.
Usually:
- if mypath is a directory (or assimilable to a directory), you get a 
redirect to mypath/ (else relative references won't work)
- for mypath/ you get the default document for that directory, maybe 
index.html or index.php or default.html or ...
- for mypath/myname you should get the best choice of documents 
regarding the Accept, Accept-Language, Accept-Encoding (but few 
people/servers use them completely).

Probably you would get a redirect to http://myhost/index.htm/

This is the

HTTPRedirectHandler doing its work. You could look at the 
Content-Location header, but I doubt you could get much more info 
about the actual object retrieved - there are proxies, rewrite rules, 
virtual hosts...
