Now it has been 2 years, I used the uploadify in my legacy system and it works good. but you need to write some hack code (such like hold the session).

I recommend you use jquery upload, which is pure HTML, no swf, no session problems and really great!

== on 2013, what I wrote:

I am considering which to choose, SWFupload or uploadify .

but on SWFupload's official website , it says that it has not been under active development and the author is hoping someday the SWFupload could revive...

so ... I decided to try "uploadify", which seems supports many options, callbacks with lots of demos. (after checking its source code, I guess the author wraps the "SWFupload v1" and "SWFupload v2" in his "uploadify v3"...)

and there's a full list of this kind of uploaders.
