| addRequestProperty | | public void addRequestProperty(String key, String value)(Code) | | Adds a general request property specified by a
key-value pair. This method will not overwrite
existing values associated with the same key.
Parameters:
key - the keyword by which the request is known(e.g., "accept").
Parameters:
value - the value associated with it.
