 Any '<' characters will normally be converted into '&lt;' for safety
 reasons. This conversion can be disabled using 'enable_html=1'.
 
+User note: IC will throw an error if you submit a CGI key without a value, ie index.html?page1 instead of index.html?page=page1. If you want to use the first style, which perl CGI supports, set TolerateGet to Yes (read up on its other effects first). The value comes through as $CGI->{page1} = undef. Since this feature is undocumented, I don't know if it can be relied on to stick around in future versions.
