Introduction
URL tags are tags that somehow use or manipulate the URL or HTTP headers. Among other things they manipulate;

`prestate options`
  Prestate options are a way to present options in the URL, that will be persistent for a user over several pages. A prestate for the options `txt` and `en` would be stored as `http://www.roxen.com/(en,txt)/my.page` in the URL. If you use prestate options you must only use relative URLs in your links.

`cookies`
  Cookies are a way for a web site to store a small amount of information in the users' browsers. It is a much better way than prestates to handle information that should be persistent for a user over several pages.

`authentification`
  HTTP can be used to transmit a user name and a password through HTTP.

`expire`
  It is possible to tell the browser, and any proxy on the way to it, how long it is to cache a page.
