Hi,
on Hiawatha 10.2, even if it force Hiawatha to cache files like jpg, css, etc. with the directive:
Directory {
  DirectoryID = expire
  Path = /
  Extensions = css, eot, gif, jpeg, jpg, png, ttf, ico
  ExpirePeriod 1 week
}
and I recall it in my VirtualHost like this:
UseDirectory = expire
It seems that files are cached up to 60 seconds, and not for the ExpirePeriod that I provided.
Why?
