Re: IPC::Cache version 0.01 available
Hi, A week or two ago, in the squid performance thread, I mentioned that I was looking for ways to eliminate squid from our production servers. I noted that we are using squid to save an expensive trip to the database to retrieve mostly static files. At that time I said that I planned to write a simple cache using shared memory that could be used with mod_perl to keep data around on the first tier. This weekend I finally had an opportunity to do just that. IPC::Cache is rather simple, considering that all the hard work is being done in the IPC::Shareable the Storable modules. I just added some basic namespace semantics and the ability to have data expire after a period of time. I'm planning on submitting it to CPAN, but I think it makes sense to make it available on this list before I do. I'd appreciate it if anyone who tries it out could send me feedback about whether it seems to do the trick. For now, you can get it at: http://unto.net/archives/IPC-Cache-0.01.tar.gz Apologies if that site is a little slow -- I'll move it over to our real servers and to CPAN in the near future. Thanks! -DeWitt Two suggestions: - Make it compatible with Apache::Session. - Try using IPC::MM rather than IPC::Shareable. It may be faster, if you don't need to store complex datatypes.

I have a similar module, but different, Tie::Cache, that I've been wanting to hook into IPC for some time. Tie::Cache is more about size based expiration, whereas you are dealing with date based.
