Re: ncat usage

Ok, I adjusted the script to output the verbatim information you've listed below using the same graphic file (also provided below). Afterwards, I tried again in the browser, but it still just shows the raw contents of the graphic file as part of the HTML. As a result, I tried an ncat on the ncat web server to see it's output, and as expected, I got the identical output below. What I did notice, and later verified as an issue with all requests, is that the connection never closes. As such, I think the original connection to the web server transmitting the HTML never closes so any output produced afterwards gets added right behind it as part of it (the graphics file request). This would also explain why the status bar never shows a disconnect from the web server. So... I changed the script once again to put ncat inside the infinite 'while' loop (and remove the -k parameter) so that it should basically serve the file and then stop running - only this didn't correct the problem! The connection still stays open when I ncat, the ncat web server! I've even tried doing an "echo -e '\x04'" (EOT/EOF) after the HTML is transmitted to the server, but it doesn't cause a disconnect either. Thoughts?
