If HTML page contains reference to external CSS file with URL beginning with '//', then host-less references in this CSS file are handled incorrectly by Portal Access.
Web application may not work correctly.
- HTML page at http://example.host/page.html: <link rel=stylesheet href=//another.host/some/path/my.css> - and this CSS contains reference with absolute path like this: html { background-image: url(/misc/image/some.png); } Portal Access uses 'http://example.host' as back-end for this image instead of correct 'http://another.host'.
Use iRule to correct back-end host.
Portal Access uses correct back-end host for references in CSS files included with scheme-less URL.
