The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.
Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP is the protocol to exchange or transfer hypertext.
The standards development of HTTP was coordinated by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), culminating in the publication of a series of Requests for Comments (RFCs). The first definition of HTTP/1.1, the version of HTTP in common use, occurred in RFC 2068 in 1997, although this was obsoleted by RFC 2616 in 1999.
HTTP functions as a request–response protocol in the client–server computing model. A web browser, for example, may be the client and an application running on a computer hosting a web site may be the server. The client submits an HTTP request message to the server. The server, which provides resources such as HTML files and other content, or performs other functions on behalf of the client, returns a response message to the client. The response contains completion status information about the request and may also contain requested content in its message body.
Abęl Makkonen Tesfaye (born 16 February 1990), known professionally by his stage name The Weeknd (pronounced "the weekend"), is a Canadian singer, songwriter and record producer. In late 2010, Tesfaye anonymously uploaded several songs to YouTube under the name "The Weeknd". He released three nine-track mixtapes throughout 2011: House of Balloons, Thursday and Echoes of Silence, which were critically acclaimed. The following year, he released a compilation album Trilogy, thirty tracks consisting of remastered versions of the mixtape material and three additional songs. It was released under Republic Records and his own label XO.
In 2013, he released his debut studio album Kiss Land, which was supported by the singles "Kiss Land" and "Live For". His second album, Beauty Behind the Madness, which became his first number one album on the Billboard 200, included the top-five single "Earned It" and produced the number-one singles "The Hills" and "Can't Feel My Face". The songs have simultaneously held the top three spots on the Billboard Hot R&B Songs chart, making him the first artist in history to achieve this.
Katheryn Elizabeth "Katy" Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and actress. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations. After being dropped by The Island Def Jam Music Group and Columbia Records, Perry signed a recording contract with Capitol Records in April 2007.
Perry rose to fame in 2008 with the release of the singles "I Kissed a Girl" – which sparked controversy for its homosexual themes – and "Hot n Cold" from her second album, a pop rock record titled One of the Boys. Her third album, Teenage Dream (2010), ventured into disco, and contained the U.S. Billboard Hot 100 chart-topping singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)" as well as the number-three single "The One That Got Away". The album became the first by a female artist to produce five number-one Billboard Hot 100 songs, and the second overall after Michael Jackson's album Bad. In March 2012, she reissued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake".

Tomorrow I will go to San Francisco
I bought the flight by accident last night
Later I´ll be dancing down in Rio
And Australia is on the other side
[Bridge]
I´m sick of this security I have with every step I ever
make
It´s like hell
Even if your words would fly like butterflies
I would not be afraid
´cause there´s nothing left to say
[Chorus]
Your commentary is not necessary
I made up my mind today
And noone can say
That it´s too far away
Coz I made up my mind today
and I´m sure
Many years have passed, they stole my longing
A trip around the world has been my dream
Behind the wall of silent hope, still waiting
That a princess in a golden cage is freed
[Bridge, Chorus]
I will taste the air on every continent
and maybe find a place to stay
I´ll think about your words when I see butterflies
and drink the best champagne
to your health
[1.strophe, Chorus(2x)]
