I’ve read literaly hundred of tutorials, samples and many more code, where they say something like: “If you have mod_rewrite do it like this, if you don’t then do this other thing”
My question is: “How possible is to find a production server without mod_rewrite?”
Apache accounts for less than 60% of all web servers (source: Netcraft Web Server Survey). That means at least 40% of production web servers do not have mod_rewrite, an Apache module.
