Abstract: According to this disclosure, a proxy server is enhanced to be able to interpret instructions that specify how to modify an input object to create an output object to serve to a requesting client. Typically the instructions operate on binary data. For example, the instructions can be interpreted in a byte-based interpreter that directs the proxy as to what order, and from which source, to fill an output buffer that is served to the client. The instructions specify what changes to make to a generic input file. This functionality extends the capability of the proxy server in an open-ended fashion and enables it to efficiently create a wide variety of outputs for a given generic input file. The generic input file and/or the instructions may be cached at the proxy. The teachings hereof have applications in, among other things, the delivery of web content, streaming media, and the like.

Abstract translation: 根据本公开，代理服务器被增强以能够解释指定如何修改输入对象以创建要向请求客户端发送的输出对象的指令。 通常，指令对二进制数据进行操作。 例如，可以在基于字节的解释器中解释指令，指导代理关于什么顺序以及从哪个源填充向客户端提供的输出缓冲区。 指令说明对通用输入文件所做的更改。 此功能以开放式方式扩展代理服务器的功能，并使其能够为给定的通用输入文件高效地创建各种各样的输出。 通用输入文件和/或指令可以在代理处缓存。 其中的教导尤其涉及网络内容，流媒体等的传送。
