Apache 301 redirects on GoDaddy web hosting

I have a shared web hosting account on GoDaddy, and wanted to do a 301 redirect with an Apache .htaccess file. For some unknown reason GoDaddy’s web interface wasn’t working for this, so I thought I’d fix the problem manually.

In short, this did NOT work:

How to access HTTP response headers after making an HTTP request with Apache HttpClient

This is an excerpt from the Scala Cookbook (partially modified for the internet). This is a very short recipe, Recipe 15.12, “How to access HTTP response headers after making an HTTP request with Apache HttpClient.”

Problem

You need to access the HTTP response headers after making an HTTP request in your Scala code.

Solution

My Scala Apache access log parser library

Last week I wrote an Apache access log parser library in Scala to help me analyze my Apache HTTP access log file records using Apache Spark. The source code for that project is hosted here on Github. You can use this library to parse Apache access log “combined” records using Scala, Java, and other JVM-based programming languages.

Analyzing Apache access logs with Spark and Scala (a tutorial) alvin March 9, 2014 - 9:21pm

I want to analyze some Apache access log files for this website, and since those log files contain hundreds of millions (billions?) of lines, I thought I’d roll up my sleeves and dig into Apache Spark to see how it works, and how well it works. I used Hadoop several years ago, and as a quick summary, I found the transition to be easy. Here are my notes.

Manual PHP and Drupal 6 web access logging alvin December 4, 2012 - 8:10am

There was a little funky activity on a client's Drupal 6 website that was hosted at GoDaddy, and without having access to an Apache access log file, I wanted to be able to see what was going on. So I wrote the following PHP code snippet to do some manual logging, and placed it in the Drupal theme's page.tpl.php file:
