Is it possible to modify HTTP headers in Oracle services?

We are wondering if its possible to modify HTTP headers in oracle services. We would like to set up Appdynamics synthetic monitoring. Here is a sample of the code snippet we might want to be injected:

<script charset="UTF-8" type="text/javascript">
window["adrum-start-time"] = new Date().getTime();
(function(config){
    config.appKey = "AD-AAB-ACJ-XFN";
    config.adrumExtUrlHttp = "http://cdn.appdynamics.com";
    config.adrumExtUrlHttps = "https://cdn.appdynamics.com";
    config.beaconUrlHttp = "http://pdx-col.eum-appdynamics.com";
    config.beaconUrlHttps = "https://pdx-col.eum-appdynamics.com";
    config.useHTTPSAlways = true;
    config.resTiming = {"bufSize":200,"clearResTimingOnBeaconSend":true};
    config.maxUrlLength = 512;
})(window["adrum-config"] || (window["adrum-config"] = {}));
</script>
