HTTP is the protocol used to access webpages on the World Wide Web. As with many early application-layer protocols, it is actually a text-based protocol, making it very easy to read and work with manually if desired. HTTP itself is an application-layer protocol that is built on top of the TCP transport-layer protocol. HTTP was developed by Tim Berners-Lee while he worked at CERN in the late 1980s as part of his project to build the World Wide Web. One of the most common of those is the Hypertext Transfer Protocol, or HTTP.

Next, let’s review a couple of application layer protocols. Hypertext Transfer Protocol (HTTP) on Wikipedia.That feature might help to identify 'missing responses' by filtering/sorting on those delta times. Please check the latest development version.Īccording to the answer of to this question, there is a functionality (implemented in bug8287) that will calculate the delta time between a HTTP request and the response. But that coding needs to be done (not very hard, but not very easy either), unless you find some ready to use Lua script for this. Within that Listener it would be possible to record all HTTP requests and check if there is a (valid) response for each request.

One idea: You could write a Lua Listener for HTTP. If you mean: There is no HTTP response to a HTTP request, then there is (unfortunately) no easy way to do that in Wireshark, as there is no HTTP protocol flow analysis, similar to TCP SEQ/ACK analysis.Ĭan you please add why you need that information (what kind of problem are you analyzing)? Maybe there is a another way to solve your problem.
