  Skipping forward (seeking) Reply Contact I remember reading that IIS7 supports seeking in the file that is being played before it downloads the whole file. As I remember the client sends GET requests for byte ranges corresponding to a seek position and the server serves the requested range. I was testing it today with a Windows Media Player 11 and skipping forward was not working until the whole file was in the local cache. IIS Media Pack is installed. Does it work with a Silverlight player only and not with a Win Media Player? Or am I missing something on the server side? Thanks, David David Bukhan

Our player (jwplayer) can be configured to send different parameters with the get-request, eg: file.mp4?start=34 to skip the first 34 seconds of the file (before the file is downloaded). What is the correct parameter when IIS serves the file? Steinar

  Re: Skipping forward (seeking) Reply Contact  "Basically your player needs to figure out the byte offsets for desired time points according the media file's metadata. " Any ideas on how to do that? A way to solve mye problem could be that my player still sends the request file.mp4?start=60 to IIS. I build a handler in IIS that maps start=xx to the correct byte-range. I (hopefully) get the right content to the player... But, how do I calculate the byte-range?
