-==Questions==
+Your modified version of tinywebserver.js should have the following functionality:
+# startup option -headers that has a comma-separated list of headers that should be logged on the console for each incoming request.
-# [4] Explain how '''and why''' the behavior of tinywebserver changes when you delete the following lines:
+# A configuration file <tt>tinyweb.cfg</tt> that allows for the port, document root directory, document aliases, and a custom 404 document.
-#* Line 50: <tt>'html': 'text/html',</tt>
+# A new 777 status code if there is a request for any document with the word "lucky" in its URL (path or document name).
-#* Line 64: <tt>docroot: '.'</tt>
-#* Line 95: <tt>return response.end();</tt>
-#* Line 126: <tt>requestpath += options.index;</tt>
-# [1] Who calls exists_callback() defined on lines 115-121?  When is this call made?
-# [1] What does the <tt>path.join()</tt> call do on line 139?  Why call this method rather than implenting this functionality inline?
-# [1] When serve_file() returns, what work has it accomplished?  Specifically what data (if any) has been returned to the requesting web client?  Why?
-# [1] What is the purpose of the code on lines 150-156 (the else clause of the "err != null" if test)?
-# [1] How can you access the incoming HTTP request headers in tinywebserver?
-# [1] Which part of tinywebserver would you change to add a new HTTP response header?
-# '''[BONUS 1]''' What do you find most confusing about the material covered so far in COMP 2406?  Note you do NOT get a bonus mark for saying "nothing"!
