Now that you've shared it, sure, but not before in the post in which I pointed 
out you didn't provide enough information.

That information was *not* in your post, so no, there was *not* enough 
information in your post.  I am happy that we found the correct answer despite 
that.  It is strange that you're claiming to have provided enough information 
by citing data that you did not provide us.

Yes, of course it can't parse a URL string of that form.  Had you included 
that datum in the original post we could have answered with complete certainty 
instead of probabilistically (and, as it turned out, correctly).  We'd have 
seen that you used backslashes in the URL string, and been able to focus right 
in on that for you.

At least we were able to focus on the string itself and the likelihood (now 
certainty) that it specified an unreachable (or outright invalid) location, 
based on the information that was available.

Thanks.  That's a good thing.
