       <h3 id="aka">AKA domain</h3>
  -    <p>An ‘AKA domain’ creates a parallel version of a site (or domain) for our redirection software so we can check redirects are correct before we put a site live.</p>
  +    <p>An AKA domain creates a parallel version of a site (or domain) for our redirection software. This allows us to preview redirects before going live.</p>
   
       <h3 id="archive">Archive</h3>
       <p>In the Transition app, ‘archive’ is a link to a page on GOV.UK with the option of either viewing the old page on the National Archive website or going to the new organisation’s GOV.UK homepage.
       </p>

  -    <h3 id="canonical">Canonical</h3>
  -    <p>The ‘canonical’ list has all duplicates removed and creates a single version of mappings to work on.</p>
   
       <h3 id="dns">DNS</h3>
       <p>The Domain Name System (DNS) connects domain names (eg www.gov.uk) with a server address. The switchover itself happens when the DNS entries for your site are changed to point at our servers, enabling our servers to redirect or show Archive pages.</p>
  
positive.code: 
      <h3 id="furl">Friendly URLs (FURLs)</h3>
      <p>A customised URL designed to be easily memorable to direct people at a specifc page with a simple title, eg gov.uk/taxdisc. These are not picked up in log files so we need to know about these in advance.</p>
  
      <h3 id="global-redirect">Global redirect</h3>
      <p>All pages on a site are pointed to the same place.</p>
  
      <h3 id="hits">Hits</h3>
      <p>Requests for a URL or document.</p>
  
      <h3 id="host">Host/Hostname</h3>
      <p>In this context, a host or hostname is the same as a domain name.</p>
  
      <h3 id="mapping">Mapping</h3>
      <p>A mapping is the relationship between an old URL and either a new URL or the decision to present an archive page to the user.</p>
  
      <h3 id="partial">Partial transition (domain)</h3>
      <p>In some situations it isn’t possible to switch an entire site over at once. This can happen in several situations:</p>
      <ul>
        <li>multiple organisations share a site</li>
  
negative.code:     <h3 id="subdomain">Subdomain</h3>
      <p>Subdomains are domain names which have a parent domain name. For example: en.wikipedia.org and www.wikipedia.org are different subdomains of their parent domain wikipedia.org.</p>
  
      <h3 id="tna">The National Archives (TNA)</h3>
      <p>The National Archives is the government organisation responsible for creating archives of UK government websites to maintain the public record in the digital age. The Transition app provides users with a link to TNA to view archived pages on transitioned sites.</p>
      <p><a href="http://webarchive.nationalarchives.gov.uk/">Web Archive homepage</a></p>
  
      <h3 id="tna-timestamp">TNA Timestamp</h3>
      <p>The National Archives Web Archive will produce snapshots (or “crawl”) of a given website, which are labelled with timestamps, for example <code>20100202072553</code> is for a snapshot taken on the 2 February 2010 at 7:25am.</p>
  
      <h3 id="ttl">Time to live (TTL)</h3>
      <p>The number of seconds for which a <a href="#dns">DNS</a> record can be cached by your computer. For example, before being checked with a DNS server. We ask for the TTL for your sites to be lowered to 5 minutes before switchover so that there is a clean cut-over — rather than different users getting the old or new site until the change has propagated. Commonly TTLs can be set to a day, which would lead to poor user experience as they would see the old or new site unpredictably.</p>
  
      <h3 id="url">URL</h3>
      <p>A URL is how a web browser requests pages, images and other data from a website.</p>
