Thats URL encoding and its required so you can pass the permissible character set used for encoding URLs is too small, and its upto the web server to decode this character sequences, and AFAICS NULL character is not part of that character set. > Seems(to me), while trying to download something with wget, it > converts the URL in browser-like format.

Thats the only way, if you try to pass NULL on request otherwise, you're trying to pass an invalid request (according to RFC), should expect an error - From server.
