let url: string = event.request.getRequestUrl();
let host:string = "https://www.example.com/";
let pos: number = url.indexOf(host);
if(pos >= 0) {
let length: number = host.length;
let rawfileName: string = url.substring(pos + length);
let type_index = rawfileName.lastIndexOf(".");
if (type_index > 0) {
let mimeType = rawfileName.substring(type_index + 1);
switch (mimeType) {
case ‘html’:
mimeType = “text/html”;
break;
case ‘js’:
mimeType = “text/javascript”;
break;
}
}
}
