The eBay website has very messy links. This site lets you make tidy links.
http://ebayitem.com/<itemnumber>
Suppose you want to direct your friend to item 160045589686 on eBay.
Normally, you would send them the very long and messy URL:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160045589686&ssPageName=ADME:B:EF:US:1
Instead, you can send them the much shorter and neater URL:
http://www.ebayitem.com/160045589686
This is a demonstration of the Apache mod_rewrite directive [view]. The toolbar-like thing is a frame [view].
