Default Value:	refresh_all_ims off
Suggested Config:
`When you enable this option, squid will always check the origin server for an update when a client sends an If-Modified-Since request. Many browsers use IMS requests when the user requests a reload, and this ensures those clients receive the latest version. By default (off), squid may return a Not Modified response based on the age of the cached version.`
