> apache apparently does not enable "accept range" by default. also see > > http://www.unidata.ucar.edu/software/netcdf-java/reference/HTTPservice.html Thanks John. Sorry for the confusion Dave. I'm still a bit unclear on some of this. It seems a bit strange as I'm seeing "Accept-Range: bytes" headers in responses from the unidata web server but can't access a netCDF file from the server (even though I can access that file on disk). I was assuming that if the "Accept-Range: bytes" header is returned then byte ranges were supported. I'm seeing the HEAD request with a 200 response in the logs (and when I do that I get the "Accept-Range: bytes" header). However, I'm not seeing a byte range request following those HEAD requests in the logs. Instead I'm seeing OPeNDAP .dds requests (which fail). Why isn't ToolsUI making byte range request? Does it depend on whether "Content-Length" or "Transfer-Encoding: chunked" is returned as well? Below are the headers I get in LiveHTTPHeaders.
