The name='array[]' syntax is useful in php which actually *uses* that sort
of syntax to assign values to an array, but the docs indicate that
hunchentoot requires you to actually specify a non-negative integer as the
index for the array value.  So, you would need to do something like
name="array[0]", name="array[1]", etc.

When clicking the submit button I see an URL like

There is absolutely nothing wrong with that.  The bracket characters aren't
allowed in a url, and so are url-encoded automagically by the browser.
