Hi
Trying to stream video to windows media player from a servlet (progressive download style). The streaming works, but I have some weird behavior, which I would like to rule out is not caused by a problem in my implementation.
When using WMP to open an url from the servlet, WMP will perform a total of 4 http-get requests for the same resource, but with slightly different headers each time. The connection for the first 3 requests seems to be closed as soon as the request (including headers) have been sent. The fourth request remains connected, and I can actually deliver response headers and the file content.
Have tried using wireshark to watch the first three requests. Identical starts of responses are sent for all 4 requests, and the first 3 requests managed to send the response headers, and some part of the file content before being closed. (Don't know if its relevant, but have to enable "Support packet-capture from IP TSO-enabled hardware" for wireshark to correctly parse the stream, otherwise the first packet containing the http-response is seen as malformed.)
The 4 request headers below here:
