java - How to fix Findbugs HTTP parameter directly written to HTTP header output -

-

i have class requestfilter , @override methods dofilterinternal. , when add header response, findbugs show error http parameter directly written http header output. how can fix problem? all.

string rqhd = request.getheader("access-control-request-headers");     response.addheader("access-control-allow-headers", rqhd); // findbugs error here

i think hrs_request_parameter_to_http_header error, , can fix that:

string rqhd = request.getheader("access-control-request-headers");  if(rqhd != null){     string rqheader = urlencoder.encode(rqhd,standardcharsets.utf_8.displayname());        response.addheader("access-control-allow-headers", rqheader); }
