Really clear and useful tutorial, thank you! I have no questions. I plan to take this idea and extend it into a URL shortener/redirect service as a project. I am making an URL shortener project. Like Bitly.com . Pretty sure I can have the LAMP stack create a flat file and then Apache will access the file for redirects. Reading DBM syntax now in the Apache docs for DBM hash . Benefitted so far from a long thread about implementing a shortener at StackOverflow . And which chars to use, also at Stack . My project is only half built (taking much longer than the three days I budgeted!). Will see if DBM mapping in Apache works.
