I'd be wary of trapping geturl. This is a handler inside libUrl that
gets called directly by the engine, and it contains some irregular
syntax.
Why not just have your own set of handlers for getting urls. Crude
example:
<...>
Sorry, no space for the isInCache, getFromCache, putInCache handlers.
:-)
And the most important - invalidateCache() and invalidateCacheEntry()
Coming up with the right strategy to do this may be the hardest part,
depending on your application :-)
It can certainly lead to some hair-pulling debugging sessions (he said,
displaying scars to prove it :-)
