hxxp://, sometimes h**p:// or _ttp://, is used in URLs (web links) to obscure the fact that one is linking to a http:// website. It is generally used to avoid automatic recognition by computer programs. For a user to follow this link, it is usually necessary to manually copy-paste the link onto the web browser's address bar and replace the 'x'es with 't's.

With Internet Explorer (including version 7), replacing the X's after pasting into the address bar is not necessary, as it will correct the URL automatically.

Some of the uses of this method include:

Sinead Houston Kerr (born 30 August 1978 in Dundee) is a Scottish ice dancer who represents Great Britain. She teamed up with her brother John Kerr in 2000. They are two-time (2009, 2011) European bronze medalists and the 2004–2010 British national champions. They placed 10th at the 2006 Winter Olympics in Turin, Italy, and 8th at the 2010 Winter Olympics in Vancouver, Canada.

The Kerrs retired from competitive skating in April 2011.

Sinead Kerr started roller skating at age 8 and began figure skating about a year later, eventually choosing the latter. She first trained as a singles skater before taking up ice dance at age 15. After her partnership with Jamie Ferguson ended, she teamed up with younger brother John, whose experience at the time was mainly in men's singles.

The Kerrs finished 2nd at their first British Nationals in 2000 and were on the podium every year afterward. Despite this, in 2003, they lost their funding from Sportscotland. Shortly afterward, they won their first British title and went on to a top ten finish at their first Europeans and 14th at the 2004 Worlds. They improved to 8th and 12th, respectively, in 2005. They were the first British ice dancers to make the top ten at the European Championships since Jayne Torvill and Christopher Dean.
