No wonder, a slash is an ISP cache problem!! Ask me and a web designer like me find it a headache because every time you update the page and upload it, if the local ISP whose Internet connexion I been using, has not cleared the cache, than I always find an old page! I have rang up my local ISP and told him to clear my cache forever but sometimes in case, if he's not cleared the cache, you have to go with a process of deleting history files and cookies n refreshing n all or if in hurry, I do is add a slash and keep adding slash as many times I update the same page.
www.extremetracking.com tracker shows the /// slashes behind its tracked urls too! I also put a no cache script someone gave me on webproworld boards but that too, doesn't work except I did a lot of shouting with the ISP help desk boys and now they are supporting me so well and clear my site caches if not done. Whenever I have this prob, first thing I do is Phone my ISP.
This site says something about this cache:

About google, maybe any other site a slash isn't required coz a surfer is not updating the google page! Its google webmaster who would need slashes behind if their ISP isn't clearing the cache!
I guess this is an answer to "What is the reasoning behind using it?"
If anyone has a different view, pls share.
