Re: [libmicrohttpd] How to record messages

[richard.hedin]

Hi, Christian. 

I've used wireshark a little bit, but I am far from expert.  Would I have 
trouble filtering out extraneous messages?  Another way to say it, can I tell 
wireshark to give me only messages to and from this particular ip and port? 

               Regards, Rick

While adding code to do this would certainly be possible, I don't think this is 
the way to do it.

If I were you, I'd use wireshark to grab the HTTP traffic on the network level 
(works also for
loopback!) and you get complete information and a nice viewer on top of it --- 
without writing any code!


Happy hacking!
