We recently restructured our media folder, moving and renaming files within it.  For the most part, everything is working correctly, but when we generate a url using Url.ContentUrl() the urls that we get seem to be built using the old file names and locations for segments, rather than the most up to date ones. 

I am assuming the urls are being cached somewhere after they are generated the first time, but it seems they persist far longer than I would have expected.  Is there a way to get the urls generated via Url.ContentUrl() to regenerate using the current file an folder names for the url segments?  

It is fine if the old urls still work, I just want all urls we generate going forward to reflect the new file structure.

Thanks!
