ParallelUserAgent (or PUA for short) is an extension of the existing libwww-5.x
|
|
distribution. It allows you to connect to download several Web pages in
|
|
_parallel_, without having to request each page one after the other.
|
|
|
|
Instead of retrieving each single page using LWP::UserAgent::request or
|
|
::simple_request methods, you first "register" all pages that you wish to
|
|
download in parallel and then call PUA's "wait" method, which will then make all
|
|
the necessary connections and download the pages.
|
|
|
|
You can define callback routines which will be called whenever a connection is
|
|
established, is cut off, new data comes in or a request finishes. The
|
|
subroutines can be global for all requests you registered, or different for
|
|
every single request.
|
|
|
|
Callbacks for example allow you to print status updates as the responses come
|
|
in, or even immediately post follow-up requests based on the responses, all
|
|
within the same single "wait" cycle.
