I am writing a lua dissector to analyze data inside a http2 packet.

f_http2_type ="http2.type")
rpc_pd = Proto("rpc_ext","rpc dissector")

function rpc_pd.dissector(buffer,pinfo,tree)

    local rpc_msg_field  = f_http2_type()

    if (rpc_msg_field.value == 0x00) then
        io.write("Type: Data")
    elseif (rpc_msg_field.value == 0x01) then
        io.write("Type: Header")


In tcp segment, http2 header and http2 data parts come together. Above dissector is called only for http2 header and not for http2 data which is in same tcp segment after header.

please suggest a solution.
