You're loading the Flash file using a relative path, which is resolved relative to the folder in the URL.
With the trailing slash, the URL is interpreted as a folder named /figures/
, without a filename.
Therefore, it tries to load load the Flash file from http://artoferichu.com/figures/figures.swf
.
Without the trailing slash, the URL is interpreted as a file named figures
in the root folder.
Therefore, it tries to load load the Flash file from http://artoferichu.com/figures.swf
.
To fix it, you can either change the page to load the Flash file from an absolute path (/Figures.swf
) or add a redirect rule for /figures/figures.swf
.
