Extend the HTTP$\_$Server by adding code to the connection$\_$handler$()$ function that breaks down the HTTP request from the client into method, url, and protocol variables. Write a concatenated response that includes the hello, method, url, and protocol variables.

The output should look something like:

HTTP$/1\mathrm{.}1200$ OK

Content$-$Type: text$/$html

Content$-$Length: $12$

Method: $\%$s

URL: $\%$s

Protocol: $\%$s

Hello, world!

End the output with two new lines $($

$).$ Your buffer variable, what you read from the client, should be $1024$ characters long. Your method variable should be $16$ characters long. Your url variable should be $1024$ characters long, and your protocol variable should be $16$ characters long. Use the sscanf$()$ function to extract information pieces from the buffer variable.
