All of them require that this directory have been 15 "make"d first. The intent is that <em>this</em> page be run 16 using:</div> 17 <blockquote><pre>althttpd -page index.html</pre></blockquote> 18 <div>and the individual tests be started in their own tab. 19 Warnings and Caveats: 20 <ul class='warning'> 21 <li>Some of these pages require that 22 the web server emit the so-called 23 <a href='https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Opener-Policy'>COOP</a> 24 and 25 <a href='https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Embedder-Policy'>COEP</a> 26 headers.
