setReferer(value: String);
The setReferer method of the JadeHTTPConnection class sets the "Referer" HTTP header.
Set the value parameter to the string value for the Referer key; for example:
"http://www.w3.org/hypertext/DataSources/Overview.html"
If the value of the value parameter is null and the Referer key exists in the list of HTTP headers, the corresponding entry is removed from the list. If the value is non-null, the corresponding value is replaced.
