Example #1: Use HTTP package

<p>This example uses the default Unix platform SSL certificates. For standard
installations, -cadir and -cafile should not be needed. Update -cadir or
replace with -cafile if your platform differs.</p>

<pre><code>
package require http
package require tls
set url "https://www.tcl.tk/"

http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs \

<h3><a name="SPECIAL CONSIDERATIONS">SPECIAL CONSIDERATIONS</a></h3>

<p>The capabilities of this package can vary enormously based upon how the
linked to OpenSSL library was configured and built. New versions may obsolete
older protocol versions, add or remove ciphers, change default values, etc.
Use the <strong>tls::protocols</strong> commands to obtain the supported
protocol versions.</p>

Example #1: Get web page

<pre><code>

# Get web page
set data [http::data $token]
puts $data

# Cleanup
::http::cleanup $token
</code></pre>

Example #2: Download file

<pre><code>
package require http
package require tls

set url "https://wiki.tcl-lang.org/sitemap.xml"
set filename [file tail $url]

http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs]
