Flowplayer and Internet Explorer (IE)

Decision

From the hypotheses there was only either player caching or movie caching. After the first experiment, it became clear that this is caching the player.
This is solved by stupidly banning caching. I did this by putting the following lines in .htaccess:
<IfModule mod_headers.c><br>
Header append Cache-Control "no-store, no-cache, must-revalidate"<br>
</IfModule><br>
<br>
# Expires<br>
<IfModule mod_expires.c><br>
ExpiresActive On<br>
ExpiresDefault "now"<br>
</IfModule>
