Python doesn't seem to have an inbuilt function to divide strings in

division operator: "Hello, world!"/3 is an array of 3-character

The different naming rules come in handy now and then. Wine creates
directories (symlinks, I think, but same diff) called "c:" and "d:"
and so on, which then become the drives that Windows pr

Which is why I believe 'return' would be a better choice, even
e for this, though, as the above call
will succeed if there is a user of that name (for instance, replacing
"/aasdfadefa" with "/rosuav" changes the response to a 200). You also
have to contend with the possibility that the server won't allow HEAD
requests at all, in which case just fall back on GET.
But all this isn't certain, even so. There are some misconfigured
servers that actually send a 200 response when a page doesn't exist.
But you can probably ignore those sorts of hassles, and just code to
the standard.
Hope that helps!

If you expect to override the health/resource, I'd us

And that's where mailing lists like this are awesome. I've learned so
much from the wisdom here... there is an amazing amount of expertise
being offered freely!
