Fix: IE limited to 30 external stylesheets

The Internet Explorer browsers cause an issue for authenticated users in our Drupal site due to a fairly major limitation around external cascading style sheets. The IE browsers are limited 30 external style sheets which is an issue in modular web sites where the stylesheets are included automatically. Usually the last stylesheet to get included and therefore the one that gets dropped by IE is the one that controls the page layout.

A recent case saw a site looking fine for anonymous visitors but no page layout for logged in visitors. The theme css file was #34.

Thankfully a module (http://drupal.org/project/unlimited_css) is available within Drupal to extend Internet Explorer's limitation.
