The response object
In response filters, this object is available as context.response. It contains a representation of the response from the HTTP server, and has the following properties:
request (object): the request object, also obtainable as context.request
responseCode (int): the HTTP status code from the server. Usually 200 indicates success, but there are many other codes.
responseMessage (string): the HTTP response message from the server, usually something like "OK" or "Not Found"
body (byte array): the body of the response, if present
bodyString (string): the body of the response (if present) as a UTF-8 string
payload (byte array): the body of the response, if present
payloadString (string): the body of the response (if present) as a UTF-8 string. If the body is not a string, this property should not be accessed.
payloadStream (object, read-only): returns a Java InputStream that can be used to read the content of the payload.
payloadWriteStream (object, read-only): returns a Java OutputStream that can be used to write to the payload.
In addition, the response object has the following methods:
string getResponseHeader(string name): returns the value of the specified HTTP header, if present. The name is case-insensitive.
boolean hasResponseHeader(string name): returns true if the specified header is set
void setResponseHeader(string name, string value): sets the value of the specified HTTP header
string getPayloadString(string enc): gets the request's payload as a string decoded using the specified encoding, e.g. UTF-16 or ISO-8859-1.
void setPayloadString(string value, string enc): sets the request's payload to the given string, encoding it according to the provided encoding, e.g. UTF-16 or ISO-8859-1.
