Logstash cors issue

Question

I'm trying to log to logstash from my client. When I try to send a post request to the logstash url, I am encountering a cors issue. I set the correct headers for the post request in the client. My logstash conf file looks like this;

input {
  http {
    response_headers => {
        "Content-Type" => "application/x-www-form-urlencoded"
        "Access-Control-Allow-Origin" => "*"
    }
 }
} 
filter {
}

output {
 elasticsearch {
  hosts => ["localhost:9200"]
 }
}

What else can I do?
