I tend to look to OneLook Dictionary Search:

https://www.onelook.com

Their set of dictionaries has multiple entries for "cacheable"
and only one for "cachable". I don't agree that the latter is
wrong exactly, because some people evidently use it and English
has no Académie Française to legislate what is right; but it's
clearly the less common spelling.
