* HTTP client that does queries in the background

|
*
|
|
* The handler method takes the following arguments: an arbitrary pointer, an
|
|
* HTTP response code, the URL queried, whether or not the message body was
|
|
* stored on disk, and the message body.
|
|
*
|
|
* If stored on disk, the body string contains the path and the file must be
|
|
* moved or deleted by the receiver when it's done. If an error occurs, the
|
|
* response code will be negative and the body will be the error message.
|
|
*
|
|
* All headers in the returned headers map will have their header names
|
|
* converted to lower case, e.g. "content-type".
|

|

* Currently only the "http" transport is guaranteed to be supported on all
