Flushing Memcached
October 11, 2007
In getting my blog off the ground, going through the 'minor-update, publish, release' cycle, I found myself needing to flush memcached to see my changes on my production server (I didn't want to wait 15 minutes for the cache to expire).
A quick google yielded the following technique:
$ telnet 127.0.0.1 11211 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. flush_all OK quit Connection closed by foreign host.
I thought that was pretty helpful.
