[CentOS] Spacewalk? Local repo? Cache?

[Eliezer Croitoru]

Hey Chris,

If you are up for the challenge you can try a hybrid of squid + local repo.
Local repo is based upon the basic nature of rsync which copies everything.
You can write a script that will filter a list of urls of mirrors and 
will prepare a "fetch" list of files which will be fetched only the 
*rpm* from one of of couple mirrors into local repo.
For each file it has in the cache it will first verify if the file 
exists in the local repo and if it is then it can redirect the client 
(transparently or with 302 redirection) into the local server.

You can use do something similar with nginx to store the file 
permanently like in the idea of:
https://code.google.com/p/youtube-cache/source/browse/#svn%2Ftrunk%2Fnginx

The main issue would be the rpms while the packages sql\xml and other 
repo related stuff should be handled only by squid caching.

Email me if it's was interesting to hear about the idea.
