Error (database) when manually typing a non-existent URI

[quote author="jdfwarrior" date="1250617261"]Checking segment by segment would probably be good. It would eliminate the possibility of errors in other areas of the uri as well. Check out the benchmarking class and see how much of a difference in performance it makes. You could always implement database caching for some of the queries as well.[/quote]

thnx
i'm diving into my codes to try and figure out how i'm going to implement all of this.
caching is a good idea to make everything faster.
