How google interprets my URLs?

[minestrone]

I have REST style ULRs on my site, like so...

http://www.mysite.com/thingId/182/th...the-thing-name

But when google indexes the site the URL it holds is..

http://www.mysite.com/thingId/182/thingName/URL%20TAG

Is there a reason why google won't keep the full URL?

I'd guess because some of the URL rewriting code on your site is busted. Never had Google do that to me.

Not sure what you've put your site together in, but is it possible it's sending 301 redirects back instead of just transferring the request on the server (eg in .NET it's Server.Transfer)?
