Is it possible to splice advertisements or messages dynamically into an MP3 file via a standard GET request?
问题 Say you have an MP3 file and it's 60,000,000 bytes, and you also have an MP3 advertisement that's 500,000 bytes, both encoded at the same bit rate. Would it be possible using an nginx or apache module to change the MP3 "Content-Length" header value to 60,500,000 and then control the incoming "Content-Range" requests so the first 500,000 bytes return the advertisement audio, and any range request greater than 500,000 begins returning the regular audio file with a 500,000 byte offset? Or is it
