Portal Access does not rewrite URLs in CSS function image-set() parameters. Browser cannot load corresponding resources.
URLs in image-set() function are not rewritten; hence corresponding resources cannot be loaded by browser.
CSS file with image-set() function or any of its variants, for example: .img { background-image: -webkit-image-set( "examples/images/image-384.jpg" 1x, "examples/images/image-768.jpg" 2x, ); }
Use iRule to replace non-rewritten URLs by rewritten ones.
Now URLs in CSS image-set() function are rewritten correctly by Portal Access. Several browser-dependent modifications of this function are supported as well: '-webkit-image-set', '-moz-image-set', '-ms-image-set' and '-o-image-set'.
