cors

Type	Description	Required	Default Value
collector	String	In default, the collected data would be reported to current domain(`/browser/perfData`. Then, typically, we recommend you use a Gateway/proxy to redirect the data to the OAP(`resthost:restport`). If you set this, the data could be reported to another domain, NOTE the Cross-Origin Resource Sharing (CORS) issuse and solution.	false	-
