then called the REST method from Postman, and opened the resulting file that RawCap created (captured.pcap in my case) in Wireshark, and it shows me some HTTP traffic: I promptly ran the newly-discovered RawCap from a command prompt with this verbiage: RawCap.exe 192.168.125.50 captured.pcap So why is Wireshark being so secretive about showing me the HTTP sent? Is it turning a blind eye to that internal communication and, if so, how can I 'unleash it' to show me that? UPDATEĪha / Voila! A combination of Postman, RawCap ( ), and Wireshark seems to work. Stream.Read(bytesInStream, 0, (int)bytesInStream.Length) įileStream.Write(bytesInStream, 0, bytesInStream.Length) Using (FileStream fileStream = fileName), (int)stream.Length))īyte bytesInStream = new byte Public async Task SendInventoryXML(String userId, String pwd, String fileName) Why are there no HTTP Protocol entries? The HTTP is apparently being sent, because I am hitting the breakpoint I've set on the first line in the server Controller method: and this with my IP Address as the source: Trying to examine further exactly what's happending (what HTTP is being sent), I run Wireshark and see only this for destination of my IP Address: Note: I get that error even though I do hit the breakpoint in the corresponding Controller REST method on the server. in Postman (using HttpPost, and attaching an xml file) and run it, on examining it in Fiddler 2, I see this error in Fiddler's Inspectors.WebView pane: Bad Request - Invalid Hostname or this one: // using IP Address of local machine

When I enter either this URI to call a REST method on my running Web API app: // using Hostname of local machine

Wireshark capture localhost traffic
