HTTP Req - display http.request_in for HTTP responses.Req # - display http.request_number, the request's sequence number within its connection (useful for HTTP-pipelined connections).Stream - display tcp.stream, the connection identifier generated by Wireshark as the file is read.
Then, I added columns for use in "eyeballing" HTTP traffic and doing quick sorting (you can sort on any column in Wireshark's display):
POSTs - apply ="POST" - display all POST requests. GETs - apply ="GET" - display all GET requests. >2s - apply http.time > 2.0 - display all responses that required more than 2s to complete. 1xx - apply 199 & 299 & 399 & 499 - display responses with server error codes. http - apply http - display all packets identified as HTTP. First, I created filter buttons for general display filters, so that I can apply them with a single click: I disabled analysis of all other protocols. Keep in mind, though, that one needs visibility at all layers of the network stack for most work in my environment, I need Wireshark to dissect Ethernet, IPv4, TCP, UDP, ICMP, SSL/TLS, HTTP, and a handful of other protocols. Disabling irrelevant protocols will greatly enhance overall performance. By default, Wireshark tries to dissect every protocol it can identify.and there are hundreds of protocols in its dissection engine. The most significant performance optimization one can implement in Wireshark is to disable analysis of irrelevant protocols. So, I set out to optimize Wireshark's performance and tweak its display for HTTP analysis. So, one could work through a Wireshark session, using display filters like =404, ntent_length > 4096, or http.time > 2.0 to display various packets.but, to be honest, I'd rather not do that much typing. I almost always have that TCP preference enabled, because the client/browser usually can't do anything with the response until it receives all of it! the end of any data returned) if that preference is disabled, http.time reflects the time between the request and the first packet of the response (i.e. If the TCP preference " Allow subdissector to reassemble TCP streams" is enabled, http.time reflects the time between the request and the last packet of the response (i.e. That last filter needs a bit of explanation, because it can be computed in two different ways.
