Issues With Web Sites

Slideshare

This web site is hosting slide shows. They are inaccessible for the crawler, so any content inside the slides is effectively lost.

Wide Designs

Some websites have been designed to only operate in a certain format, landscape or portrait. Currently the preview window is not aware of this.

Hostile Takeover Protection (JavaScript)

Some web sites detect whether they are displayed within a frame. Some redirect you to that site automatically. Some refuse to be rendered.

Corrupt MIME Types

Some sites choose not to send the correct MIME type, forcing the browser to download the object, instead of rendering it directly in the previewer.
