LIS 525 - Slow Page Demonstration

This page illustrates the kind of problem that can be created for a site if its pages include files from another site. If the other site is down, slow in responding, or no longer in existence, pages from the first site may take an unusually long time to display. In the case of this page, a single inline image with a source URL that does not exist means that the page is not fully displayed for some time.

This image will never load, because it doesn't exist.

You will generally see your browser render the rest of the page but leave a blank space for the image until it is sure that the image is not available. In this demonstration, delay is caused only by an invalid top-level domain (zz) and so is quite short. A URL correponding to a valid server that is simply slow in responding could cause a much longer delay.
