This sets up two HTTP servers on port 3000 and 3001. The one on port 3000 works as expected, the one on port 3001 doesn't.

Console log output when requesting server on port 3000:

------- NEW WORKING REQUEST -------
New listener added: end
adding 1st data litener
New listener added: data
New listener added: data
New listener added: readable

Find all files excluding a single directory:

find . -path ./exclude-this -prune -o -type f -name '*.js' -print

Notes:

• The -path ./exclude-this -prune -o part ensures that the path ./exclude-this isn't included
• The -print part ensures that the base directory of the excluded path isn't outputtet (this isn't needed if combining with -exec)
