Checking the host certificate for validity is recommended.<br>
Readers may wish to contrast with the [[HTTP Request]] task, and also the task on [[HTTPS request with authentication]].<br>

=={{header|zkl}}==
Using the cURL library to do the heavy lifting:
<
zkl: var data=ZC().get("https://sourceforge.net")
L(Data(36,265),826,0)</
get returns the text of the response along with two counts: the bytes of header in front of the html code and the byte count of stuff after the end of the page. So, if you wanted to look at the header:
<pre>zkl: data[0][0,data[1]).text
