问题 I want to create shortened links for specific pieces of content on my site. To view these pages now, I pull the relevant content via the content ID passed via GET (ie, mysite.com/content/?id=332). To obfuscate the ID, I want to use base64 to encode and decode it into a short alphanumeric string (like 34sa6), which I already know how to do. My question is this: does it make more sense to store this string as a database field on creation of each piece of content, or simply decode the string on

For example, a user might add an item and the resulting url would be something like: http://example.com/item/abc I was hoping for the unique identifier to be made up of 3 or 4 characters, where the characters are letters and numbers.
