All,
I'm sorry for using users@ as my own personal Google but I'm sure
someone knows this off the top of their head and can save me a lot of
reading.
I'm wondering about which specs mention how to handle URL parameters
(and POST parameters, for that matter) in terms of ordering. For
example, if I have a URL like:
https://example.com/context/resource?a=1&b=2&c=3&a=6
(Note that I have "a" in there twice)
If I call request.getParameterNames(), is there a predictable order in
which those parameters will be handed back? I'd love to hear that not
only are they returned in "URL order" (that is, the left-most parameter
is the first returned in that enumeration) in Tomcat, but either the
servlet spec, the CGI spec, or some other spec dictates that order
explicitly.
Similarly, if I use request.getParameterMap and than iterate through the
keys or Map.Entry objects in it, does that behave predictably as well?
I have a situation where both URL parameters and POST parameters being
in URL-order (or document-order for POST parameters) would be highly
convenient, but I'd like to know if I can actually *rely* on that
behavior, or if I have to make arrangements to provide the ordering in a
separate parameter.
I'd like to know which specs mention these things if they are indeed
specified in any of them.
Thanks in advance,
-chris
