Cookies with GetQuery?

[Bill van Melle <bi...@gmail.com>]

Is there any kind of cookie jar facility for GetQuery?

I didn't find anything in the API, so I'm guessing I have to roll my own --
parse the set-cookie fields out of query.getResponseHeaders(), and add them
to the query.getRequestHeaders() dictionary on each call.

Yes, that's right - you can use setSerializer() to return different types of content from a GetQuery, including images. 

Connection management (or at least execution management) is handled by ExecutorService:

  http://download.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html

The default executor service will start a new thread per query, so the number of queries is limited only by system resources. The JDK provides additional executor services that you can use to manage and constrain query execution.

Thanks.  After I wrote this message, I feared I might have to roll more than
just my own cookie jar, since I realized I have some web calls that need to
fetch images, and others that have junky legacy unstructured (non-JSON)
returns.  But then I noticed Query#setSerializer.  So I should be able to do
something like

GetQuery q = new GetQuery("hostname", "/getImage?id=23");
q.SetSerializer(new BufferedImageSerializer());
q.execute(new TaskAdapter<BufferedImage>(new TaskListener<BufferedImage>() {
.. }

to get an image out of a web call that returns jpeg content, right?  Very
cool if so.

What sort of connection management is exposed, if any?  For example, how
many outstanding GetQuery's can one have at a time?  Can I set the limit?
 So then GetQuery#execute blocks in the background waiting for a
connection if the limit is currently exceeded?

Correct. Web queries don't support cookies because they are geared primarily towards REST services, which are generally meant to be stateless. However, it is possible (and fairly easy) to implement your own cookie support.
