There is definitely more than one way to do it, but mixing GET and POST is still wrong -- though I realize you're not advocating that here. GET and POST are not the same and shouldn't be used as such. In this post, I wrote:

As a general rule of thumb, use GET when you get information from a server without changing it. Use POST when you post information to a server and thus change it. That's why we have two methods.

That's the rule of thumb to remember, but there are technical distinctions as well. See the aforementioned link for a bit more information. Blindly mixing the two usually doesn't cause problems, but like so many issues of its kind, the intermittant problems that can result are very difficult to diagnose.

Cheers,
Ovid

Update: Ugh. I just read kha0z's original post. Amongst other things, /s?he/ advised "Parse the query string yourself yourself." This is bad. Very bad. First, not only does CGI.pm parse the query string for you, thus causing your parsing of the query string to be rewriting code, but the "roll your own" parsing that kha0z suggested is terribly broken.

Obviously, I can't be that good of a programmer if I failed to note the "context" of the node I was replying to :)

    For one, you can only get resumable downloads with GET and not POST
