cvLoad can't read urls.

and besides, downloading it from a webserver looks like a bad idea. instead, bundle the xml locally with your client code.

<strike>how do ppl get your program ?</strike>

i mean, they need to get the xml only once. (not with every detection)

you'd have to use libcurl, or any other http-utility lib for the download.

if you're using old-style cascades(made from cvhaartraining), you'd have do save it to a file, and load it the usual way, if it's a new-style one (made from opencv_traincascade), you can pass it in memory
