Hi, I need to install Squid on a vessel that uses slow radio and satellite connections. Sometimes there is enough bandwidth, but usually it is below modem speeds. There are a few (dozen) very large files that need to be cached in a special way: Squid must ignore all attempts to fetch newer versions of these listed files from source unless... - the object is completely missing from cache OR - there is enough of bandwidth (or alternatively: the time is between xx:yy and zz:vv) The fact that these files might have changed does not play a role. The old version must be served from the cache untill the bandwidth is back again. How do I implement this? I could use some wget + scripting magic, if needed... Thanks.
