Assertion:
Netscape and Opera both ignore improperly terminated URLs used as the BASE HREF value. eg: relative URLs in a document that used "http://www.blooberry.com" as the HREF would resolve to "http://[relative URL]", and "http://www.blooberry.com/indexdot" would resolve to "http://www.blooberry.com/[relative URL]". To prevent this problem, use a trailing "/" character to properly terminate the URL. Internet Explorer, by the way, accepts both URL forms.

BASE element refers to "http://www.blooberry.com/indexdot", hyperlink refers to "index.html"
(Should link to the blooberry.com site main page instead of the Indexdot main page like you might expect):

filler text Link to "index.html" filler text
