No, it is not possible to force Squid to align HTTP message data made available to adaptation services. If you have to do something like that, you might be able to shape the incoming TCP data into properly sized packets before Squid reads them, but even if you are successful at that difficult task, Squid may aggregate or split TCP payloads for various reasons. > If that is not a current capability then is that an acceptable > feature someone could join and contribute? I do not think so: In eCAP, it is the adapter that pulls message body data from the host application! The host application (in your case Squid) does not push data into the adapter. Thus, an adapter can pull as much or as little as it wants, observing whatever "alignment" it needs. > 2.

No, not directly: eCAP does not know anything about files, songs, and scroll bars. It works at the lower HTTP level while you are asking about higher level metadata that would be specific to the playback protocol/method being used on top of HTTP. > Dumping and looking at the chunk contents in method > noteVbContentAvailable I don’t see any HTML that indicates any > offset/position/range. And in start enumerating the HTTP header entries > I don’t see any such either (adapted->header().visitEach(*visitor);). *If* the plugin/code in the client browser has requested something special after the "scroll bar is jumped to the end of the song" event, then that special request will be reflected in HTTP request headers and/or body. It could be the request URL itself, the Range header field, some custom request header, or even something inside a POST request body. All those things _can_ be analyzed by an eCAP adapter code, using existing eCAP APIs, of course. It is adapter responsibility to map those HTTP concepts to playback position or any similar applicaction-specific info.
