[REQ] Simple rest client with digest authentication support

[eluser]CARP[/eluser]
Hi
I'm using this code from Phil Sturgeon to make a little API for an application I'm developing:

https://github.com/philsturgeon/codeigniter-restserver

Now, I'm looking for some simple code (not a complex rest client) to use this api.
I've found many, but NONE of these (classes, snippets, etc.) support "digest" authentication mode

Does any1 know any?
I don't want (maybe later) to develop a full codeigniter (or other framework) based client to access the api, just want to try it with a couple of php files

Thanks,
