The new network protocol: HTTP/2, which has been published in RFC7540 in May 2015, is now be expected by more and more people to provide better performance than HTTP/1.1 in multiple aspects, i.e. the header compression and server push in reducing the web page loading time. Although HTTP/2 server push can make the web page load faster, this new update function may cause the server to push the same resources repeatedly, or lead to a slower transmission of push resources, resulting in incorrect judgements of lost resources and the corresponding duplicate resource requests. Accordingly, this research aims to use the session mechanism to prevent the problem of repeated push of same resources when a client is already cached resources. Queue and stack are further used to avoid unnecessary transmission wastes of resources and streams that may occur when client browser incorrectly interpret servers’ responses of index.html file as missing file resource under the circumstances of some network delay or slower network speed.
