I can do http.post using simple variable values but I'm having some problems with http.post using base64 encoded data.

For example, if I set 'somedata' to a simple string, the following code works. But if I take more complex data (like rsa signature) and encode it using Base64.encode64(somedata), I get a "permission denied" web server message.

I'm wondering if this is caused by base64-encoded data resulting in some '=' characters and if so, how do I work around this?
