Really this is for Mac OS X, but I figure I can apply linux thinking to the topic.
So thinking in terms of Linux, is it possible to do the following, and if so how?
What I want to do is be able to type something like http://localhost/
(though something different would be used) and have it redirect me to http://localhost/some/subdirectory/.
I don't know much about Apache, or anything else to do with servers, but this is the easiest way for me to implement a free database at work for keeping track of lab cultures, enzymes, etc (microbiology lab stuff). Right now I have it working great, with PHP. mySQL and Apache running perfectly together, but the people I work with won't use it unless it is incredibly easy to use, so having a long url to remember won't cut it.
We also use 3 different web browsers, so putting bookmarks in them works, but isn't the best solution. I was thinking if it was possible to just set something like http://labdb/
to redirect to the database that would be awesome, unfortunately I don't know how to do this.
