I'm trying to understand how to use the HTTP utilities, and I'm having trouble just creating a session. I get a Web Service session manager not found error. I've read where the client has to support cookies. My eventual client will be a labview VI that talks to a web server. I llooked at the Tools:Options, but don't see anything related to cookies. Not sure if that's what's causing this anyway, but I'm just digging. Also, I want to eventually send http messages across TCP/IP. Do I need to use the TCP/IP VIs (i.e. open connection, etc) or do I use the http utilities alone. If both are needed, how does the httpRequestID and the TCP/IP connection ID correlate.
