Multiple other properties are available for setting up, tracking status and checking result or UnityWebRequest.
UnityWebRequest wr = new UnityWebRequest(); // Completely blank
UnityWebRequest wr2 = new UnityWebRequest("https://www.mysite.com"); // Target URL is set
// the following two are required to web requests to work
wr.url = "https://www.mysite.com";
wr.method = UnityWebRequest.kHttpVerbGET; // can be set to any custom method, common constants provided
wr.useHttpContinue = false;
wr.chunkedTransfer = false;
wr.redirectLimit = 0; // disable redirects
wr.timeout = 60; // don't make this small, web requests do take some time
