What have you tried so far, and what are you trying to do?  It *looks =
like* you're dealing with some kind of HTTP request with an extra \r\n =
between the Get line (method tokens in HTTP/1.1 are case sensitive).

To simply achieve your end as stated you might do:

ratdog:~ mike$ pry
[1] pry(main)> query =3D "Get /index.html HTTP/1.0\r\n\r\n"
=3D> "Get /index.html HTTP/1.0\r\n\r\n"
[2] pry(main)> query +=3D "Host: www.example.com\r\n"
=3D> "Get /index.html HTTP/1.0\r\n\r\nHost: www.example.com\r\n"
[3] pry(main)> query +=3D "Connection: Close\r\n\r\n"
=3D> "Get /index.html HTTP/1.0\r\n\r\nHost: =
www.example.com\r\nConnection: Close\r\n\r\n"
[4] pry(main)> query.split(/(?:\r\n)+/)
=3D> ["Get /index.html HTTP/1.0", "Host: www.example.com", "Connection: =
Close"]

But if you care about multiple \r\n sequences, which are used to =
separate the header from the body of an HTTP request, you should think =
about what you want to do with malformed input.

If you're doing this for your own education and enlightenment then it is =
a good exercise, if you want to write an application then you might want =
to look for gems which can process HTTP requests.

Hope this helps,
