The HTTP Component allows you to execute a HTTP Get or Post operation.

For a Post operation you can configure the request content (as a string or byte[] variable containing the request data - the Encoding property available in the Visual Studio Properties window can be used to define the mapping between string content and request binary).

For both Get and Post operations you can specify a variable to hold the response content. Again this can be a string or byte[] variable, with the Encoidng property defining the conversion between the binary response and string content.

The URL and other connection details, for example authentication and proxy server options, are configured via a +HTTP Connection. The Connection dropdown includes a <New Connection> option that you can use to create a new +HTTP Connection.  The following form is presented, from which you can configure all relevant details.
