Then the WebInject program also shows errors when using the browser at the same time?
Yes. The WebInject shows errors where it receives no response to its GETs.
And yes I'm aware of favicon.ico. Actually Firefox sends 2 GET requests for favicon.ico when it renders a page for some reason??
I thought of trying two or more instances of WebInject - just need to get my hands on another machine.
EDIT : Maybe we can look at this another way. Has anyone got a sketch which shows that 4 server sockets can be connected and work at the same time??
