Almost Done

So, I'm almost done but am going to continue tomorrow. Here's what's been changed:
1) Write request to log file has been completed and all logs are writing correctly.
2) The client cannot change directories.
3) If they request an invalid file, the 404 HTTP page is sent.

What needs to happen:
1) The Modified since is not working correctly. Normally the ifMod never gets changed and then it can't be parsed.
2) The timeout is not working correctly yet. For some reason, it just doesn't time out.
