Yes, as I mentioned earlier many software libraries and utilities have
catalog options which you should explore.  If not you can put up a
caching proxy up in front of your application.  There really is no need
to have it repeatedly request the same resource across the internet.
You should also find doing this the right way (wrt HTTP caching
directives or catalog) should dramatically improve performance.
