Large downloads of gzipped files may be incomplete when a HTTP/2 profile is added to BIG-IP virtual server configuration. With a "Connection: close" response header, the BIG-IP can close the uploading client-side immediately, before completing the download of the requested file.
When downloading a large gzipped file using HTTP2, the download may fail to complete.
- HTTP/2 client-side profile. - HTTP response containing the "Connection: Close" header. - Large server-side gzip compressed and chunked response payload.
Enable connection keep-alive on the pool member's http server. Alternatively, remove "accept-encoding: gzip" header from client request or configure "response rechunking" on http profile.
Downloading large gzipped file using HTTP2 will successfully complete.
