Yum has error on primary.xml.gz or similar when behind squid. (clearing and reloading a URL in Squid)

Verify the entry is getting hit in your cache by watching your logs

TCP_MEM_HIT/200 1597 GET – HIER_NONE/- application/x-gzip (or similar)

To reload this entry run

squidclient -r


To clear this entry

squidclient -m PURGE

You can also whitelist this inĀ  several ways if you do not want this to be cached or do not want it cached for long (ie 24 hours) but I will save that for another post.

Caching packages and yum related information in squid can be helpful if you have a large number of machines behind a company/personal proxy and have limited (either in speed or monthly amounts) bandwidth at your location. While running a local mirror is preferred for many reasons this could fill that role till such time as you feel you need the complexity of local mirror.
