[users@httpd] memory-mapping and updating cached content in RAM question

["Rose, John B" <jb...@utk.edu>]

Red Hat 7 Apache 2.4.6
Filesystem is local

How does updating the cache in RAM of frequently viewed pages with MMapFile work if you change sections of
the page frequently, but say 75% of page stays the same?  Like calendar
Items on the page. Or news releases. Since that is common nowadays.

Do we have to restart Apache to update the cache?

Thanks

The manual says "When the files have changed on the filesystem at
least a HUP or USR1 signal should be send to the server to re-mmap()
them."
