To work with some endpoint, sometimes we need to pass additional information to requests such as authorization information, cache control information, API version, etc.
ShortPoint REST API and Web Service (XML) connection types have Custom headers function under Enable Advanced Settings section which allows you to set up all required headers:
Let's assume that you want to force caches to submit the request to the origin server for validation before releasing a cached copy. So you need to add Cache-Control header with value no-cache to HTTP request.
To do this, you need to set up headers object in Custom header function in the following format:
headers["<Header name>"] = <Header value>
For our case we get the following:
headers["Cache-Control"] = "no-cache";
Note: Headers object can accept as many headers as you want and all of them will be added to the HTTP request.
After you are done, click Connect and finish up the connection setup.
That's it. Happy connecting!
