A rewrite engine is software that modifies a web URL’s appearance (URL rewriting). Rewritten URLs (sometimes known as short, fancy URLs, or search engine friendly – SEF) are used to provide shorter and more relevant-looking links to web pages. The technique adds a degree of separation between the files used to generate a web page and the URL that is presented to the World.

Hotlinking
Hotlinking (also known as Inline linking, leeching, piggy-backing, direct linking, offsite image grabs, bandwidth theft) is the use of a linked object, often an image, from one site by a web page belonging to a second site. The second site is said to have an inline link to the site where the object is located.
Website builder
Website builders are tools that allow the construction of websites without manual code editing. They fall into two categories: on-line proprietary tools provided by web hosting companies, typically intended for users to build their private site; and software which runs on a computer, creating pages off-line and which can then publish these pages on any host. (The latter are often considered to be “website design software” rather than “website builders”.)
