Sending large chunks of data

[floatpointer]

I'm currently creating a client that tries to send a large chunk of data (a PDF as a Base64 encoded string). I do manage so send a small string using the send method. But it fails with ""The sending has been interrupted." when trying to send the PDF (using myClient.Send(string) ).

I've also managed to create a server (using websocket-sharp) that when requested by a client returns the PDF using the Send method and this works without any issues.

I've also tried using the SendAsync without any success...

Any pointers? I assume that there's some limitation in the client's send capabilitites?
